## Description

YOKOCUT Cobalt Step Drill Bit for Stainless Steel and Hard Metal, High Speed Steel 6% Cobalt Step Bit with AlTiN Coating, Cone Drill Bit Multiple Hole Cutter (4-32mm, 15 Steps) : desertcart.co.uk: DIY & Tools

Review: cuts very well for the price point - cuts thorough high quality starless steal 3mm sheet like butter with cutting oil. had been struggling with some cheaper and more expensive drill bits and this did the job nicely.
Review: Sharp, strong, cuts easily and stays sharp after multiple uses. Recommended. - I've used cheap step drills for years, but they never last. I bought this to drill some 30mm holes in 4mm galvanised steel plate. With a slow drill, plenty cutting fluid and a pilot hole, it made short work of 8 holes. When I'd finished it was pretty much as sharp as when I started. Since then I've used it for other holes in stainless steel, it's still sharp and drills easily. The 3 flats on the shaft ensure it locks securely in the chuck. Highly recommended. I was unsure if it was worth the extra over the cheap ones, but it certainly was 👍

## Questions & Answers

**Q: Can anyone tell me if this is likely to be able to ream out a saw blade that is 1mm thick and made from HSS steel? TIA**
A: Hi there, this 4-32mm step bit is made from HSS Cobalt M35 material, which means it has a hardness of HRC 65-67° reinforced by the AlTiN coating. Therefore, for a common saw blade, considering the hardness and thickness of it, and based on the infomation you provided, the YOKOCUT 4-32 step bit with AlTiN coating and cobalt construction will definitely ream it out. We recommend you should start with lower RPM and using lubrications such as water and oil.
