Constructed from tungsten steel carbide, a material noted for its hardness and ability to maintain a sharp cutting edge, these drills are built to handle the repetitive, precise hole creation required in such fields. Available in two focused size ranges—0.1-1mm and 0.3-1.2mm diameters—they cater to the fine tolerances needed for component leads and vias. With a compact 36-38mm total length and a standard 3.2mm round shank, they are designed for use in precision drill presses, CNC milling machines, and hand-held rotary tools with appropriate collets.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Tungsten carbide straight shank PCB drill bits in sizes from 0.1mm to 1.2mm with 3.2mm shank.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/1279\/2025-09-30\/original-image\/132565927681.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe design of these drills centres on delivering consistent performance for small-diameter, high-precision drilling tasks. Every specification is geared towards stability, accurate sizing, and material compatibility.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe drill body and cutting edges are made from tungsten steel carbide. This material choice is directly linked to the stated capability for achieving maximum cutting depth in tungsten steel itself, indicating a high level of hardness and wear resistance. This makes the drill suitable not only for PCBs but also for drilling other hard, abrasive, or delicate materials where a sharp, durable edge is necessary to prevent tearing or deformation. The fixed shank and twist flute design provide the structural integrity needed for high-speed rotation and clean chip evacuation.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eThe drills are categorised by two key dimensional groups. The overall package is compact, with a total length of 36-38mm, allowing for use in confined spaces and on benchtop equipment. The useful blade length, or cutting depth, ranges from 1.5mm to 10.5mm, providing flexibility for creating shallow pilot holes or drilling through standard-thickness PCB substrates. The most critical user specification is the shank diameter, which is consistently 3.2mm across all models. This round handle design ensures compatibility with a wide range of commercially available toolholders, collets, and chucks designed for micro-drills, offering a secure grip to minimise runout and maximise drilling accuracy.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Tungsten carbide straight shank PCB drill bits in sizes from 0.1mm to 1.2mm with 3.2mm shank.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/1279\/2025-09-30\/original-image\/1622768717737_13f7c35a-0732-4106-94ce-de1b17f5c188.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThese drills fill a specific niche in workshops, production floors, and hobbyist spaces where accuracy on a miniature scale is non-negotiable.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eIn professional and industrial settings, such as electronics manufacturing facilities and precision engineering workshops, these drills are consumable tools for PCB prototyping and production. The specified size ranges cover the most common hole diameters needed for through-hole components and vias. The tungsten carbide construction supports longer tool life in high-volume environments, reducing changeover frequency. Their use extends to creating precise holes in other non-ferrous metals, ceramics, and composites where standard HSS drills might wear quickly or cause material damage.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor modellers, jewellery makers, and advanced DIY electronics enthusiasts, these drills enable detailed work that standard tooling cannot achieve. They are ideal for drilling pilot holes for fine screws in scale models, creating openings for wires and LEDs in custom enclosures, or working with other small, delicate materials like acrylic or thin brass. The availability in packs of 10 means a user has spares on hand, which is practical for small-diameter tools that can be prone to breakage if misaligned or subjected to lateral force.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Tungsten carbide straight shank PCB drill bits in sizes from 0.1mm to 1.2mm with 3.2mm shank.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/1279\/2025-09-30\/original-image\/2627055695308.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe value of these drills lies in their specialised design, material quality, and the practical packaging that aligns with their use-case.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eThe primary benefit of the tungsten carbide material is its inherent resistance to wear and deformation under heat. This translates to a drill that can be used for multiple jobs without a significant drop in performance, assuming it is used correctly within its capacity and stored properly. Unlike some high-speed steel drills that may require frequent sharpening, these carbide bits maintain their cutting geometry for longer under typical PCB drilling conditions, offering a practical advantage in terms of consistent hole quality over time.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eChoosing this product comes down to matching a specific need: drilling very small, clean holes in hard or delicate materials. The concrete specifications—the 0.1-1.2mm diameter range, the 3.2mm shank, the tungsten carbide material, and the 10-piece minimum pack—provide a complete picture for a buyer. It is a focused tool for a focused task, avoiding the compromises often found in general-purpose drill bit sets. The packaging in quantities of 10 recognises that these are consumable items in a professional context and provides cost-effective spares for a hobbyist, making it a practical purchase for anyone regularly engaged in precision micro-drilling work.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Tungsten carbide straight shank PCB drill bits in sizes from 0.1mm to 1.2mm with 3.2mm shank.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/1279\/2025-09-30\/original-image\/5380c854-219d-47fa-b5e8-f317070bd63a_f3d23b2e-b2e2-4261-a2b9-f4526a78eb40.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Tungsten carbide straight shank PCB drill bits in sizes from 0.1mm to 1.2mm with 3.2mm shank.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/1279\/2025-09-30\/original-image\/75906036071572.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Tungsten carbide straight shank PCB drill bits in sizes from 0.1mm to 1.2mm with 3.2mm shank.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/1279\/2025-09-30\/original-image\/c383849a-d0d2-4b2c-a755-fbba6c04f34d_29de6592-d4c7-47af-a8d6-a4a09ee4678a.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Tungsten carbide straight shank PCB drill bits in sizes from 0.1mm to 1.2mm with 3.2mm shank.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/1279\/2025-09-30\/original-image\/c56d40c8-5177-4e8a-9df6-61caaf915b1a_d387c80f-33e9-4a14-8bc5-85e887bc7d23.webp\"\u003e\u003c\/div\u003e","brand":"5mn5u0-4f","offers":[{"title":"5style \/ Q10pcs","offer_id":57525599535486,"sku":"CJJZGJSD00908-5style-Q10pcs","price":25.75,"currency_code":"GBP","in_stock":true},{"title":"4style \/ Q10pcs","offer_id":57525599568254,"sku":"CJJZGJSD00908-4style-Q10pcs","price":25.75,"currency_code":"GBP","in_stock":true},{"title":"1style \/ Q10pcs","offer_id":57525599601022,"sku":"CJJZGJSD00908-1style-Q10pcs","price":21.75,"currency_code":"GBP","in_stock":true},{"title":"3style \/ Q10pcs","offer_id":57525599633790,"sku":"CJJZGJSD00908-3style-Q10pcs","price":23.75,"currency_code":"GBP","in_stock":true},{"title":"2style \/ Q10pcs","offer_id":57525599666558,"sku":"CJJZGJSD00908-2style-Q10pcs","price":21.75,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/0150\/6942\/files\/1047573745177.webp?v=1780928309","url":"https:\/\/lindenmere.co.uk\/products\/straight-shank-twist-drill-with-tungsten-steel-carbide-fixed-shank-for-circuit-board-drilling-small-diameter-drill-bits-in-0-1mm-to-1-2mm-range-36-38mm-total-length-with-1-5-10-5mm-cutting-depth-and-3-2mm-round-handle-diameter-for-precision-pcb-work","provider":"Lindenmere.co.uk","version":"1.0","type":"link"}
