1mm Drill Bits

Achieve pin-point accuracy for delicate tasks and precision engineering with our range of 1mm drill bits. Essential for creating minute pilot holes or working with intricate components in electronics and model making, these micro-diameter bits ensure clean entry points without splitting or damaging the material. Whether you are tackling fine detail work in the workshop or preparing surfaces for tiny fasteners, these bits are designed to maximise control and reduce wandering.

Our selection includes durable High-Speed Steel (HSS) bits for general purpose drilling and titanium-coated options that offer superior resistance to heat and wear. Although small in size, these accessories are built to withstand the demands of professional use, minimising the risk of snapping when used correctly. We stock reliable kit from trusted trade brands including Abracs and Draper.

Frequently Asked Questions | FAQs

What is a 1mm drill bit used for?

A 1mm drill bit is primarily used for extremely fine precision work, such as drilling Printed Circuit Boards (PCBs), model making, jewellery crafting, and creating pilot holes for very small screws. They are crucial when working with delicate materials where a larger bit would cause cracking or splitting.

How do I stop 1mm drill bits from snapping?

Due to their thin profile, 1mm bits are fragile. To prevent snapping, use a high RPM speed with very light pressure and ensure the drill is held perfectly perpendicular to the surface. Using a pillar drill or a rotary tool stand is highly recommended to eliminate the hand wobble that often causes breakage.

Can I drill metal with a 1mm HSS bit?

Yes, 1mm bits made from High-Speed Steel (HSS) or those with a titanium coating are suitable for drilling into metals like steel, aluminium, and brass. However, because the bit is so thin, it is vital to use a cutting fluid to keep the bit cool and prevent it from binding in the metal.
