1/4"-2" M2 Step Drill Bit Unibit for Hole Drilling 10 Sizes M2 High Speed Steel; Double Spiral Flutes; Fast, Clean Cuts in Stainless Steel, Copper, Aluminum, Wood, Plastic

[M2
HSS]: Cuts considerably cleaner holes and much more easily than standard step bits. In general, M2 contains 50% more Tungsten and 150% more Molybdenum, both of which are essential elements for improving durability. Additional vacuum heat treatment and nitride surface hardening further enhance performance.
[Non-stop]: Polished steps and size markings let you see the target hole size while drilling. No need to pause mid-drilling to check. Saves you time and effort. [Easier | Faster |
Cleaner]: With high-accuracy CNC processing and several refined design details developed over the years, this design cuts easily, quickly, and cleanly, outperforming typical bits on the market.
[Heavy duty]: Cuts holes in stainless steel (with appropriate pressure), hardened metal, mild steel, galvanized steel, aluminum, copper, plastic, wood, or any material with similar or lower hardness. Up to 12ga / 2.7 mm thickness for stainless steel.
[Multi Hole Sizes]: No need to purchase a set. This single step bit includes 10 marked sizes, allowing you to drill 10 different hole sizes, saving time and effort in changing bits.
Marked sizes include: 1/4", 3/8", 19/32", 3/4", 1", 1-3/16", 1-3/8", 1-5/8", 1-3/4", 2"
