Description
Our other bit packs give you ten of one size, which is what you want once you know the size. This is for before you know it: ten different sizes stepping through a range, so the hole you need is already in the box.
Tungsten carbide, 3.175 mm shank on every bit regardless of the cutting diameter.
Starter kit: 30 bits, 0.1 to 2.5 mm, $39.99
Not sure which range you need? Take the starter kit: three sets in one order - 0.1 to 1.0, 1.1 to 2.0 and 1.6 to 2.5 mm, thirty bits in all. Bought separately those three sets come to $55.97. It covers board work, through-hole parts and small brass in one go.
The uniform shank is the point
A 0.3 mm drill with a 0.3 mm shank cannot be held by an ordinary chuck at all, and it snaps the moment it is not running true. These are ground down from a 3.175 mm body, so every bit in the set clamps the same way, runs concentric, and has a solid shoulder behind the cutting end. Our chuck takes 0.3 to 4 mm, so the whole range fits without changing anything.
Choosing a range
0.1 to 1.0 is board work - vias, fine component legs, watch and model parts. 0.6 to 1.5 covers most through-hole components. 1.1 to 2.0 and 2.1 to 3.0 move into general small-part drilling where you want a step between sizes rather than one size repeated.
How to run carbide
Carbide holds an edge far longer than HSS. Clamp the work and drill straight down - carbide dislikes side load. Run them fast and feed them lightly: a slow feed, not a slow spindle, is what keeps the tip sharp. The finest sizes, below about 0.5 mm, are consumables.

Before you order
Do I pay tax or duty? In the United States, sales tax is added at checkout where your state charges it, and the total you see is what you pay. For Australia and New Zealand nothing is added at checkout. If a carrier ever asks you for a fee on one of our parcels, don't pay it: email us first and we sort it out.
What if a part breaks? For twelve months, tell us which part and we post a new one free. No return needed.
Can I cancel? Yes, within 24 hours of ordering, no questions asked.
