## Description

desertcart.com: TEMO M35 Cobalt Spiral Flute Step Drill Unibit, 13 Size 1/8 Inch To 1/2 Inch, 1/4 Inch Hex Shank : Everything Else

Review: Best step-drill I've ever used! - This is very well sharpened and cuts through hard Subaru structural sheet metal with ease. Though I haven't put it to a severe test I see no reason why it wouldn't perform well. I'm an ex-machinist and model maker and I think many users and some reviewers don't realize what these bits are best at doing and also don't use any lubricant and probably spin them way too fast. When used properly they should last for punching clean holes in sheet metal. It's always good practice to drill a small pilot hole (like 1/16" to 1/8" diameter) before enlarging it with the step drill.
Review: Good - Good price and works great as a metal bit. Makes clean holes and is very durable.

## Features

- M35 cobalt step drill, 1/4" (6.35mm) hex shank, 13 holes: 1/8" (3.175mm) to 1/2" (12.7mm)

- Double spiral flutes for more efficient swarf clearance; 1/4 Inch hex Shank with quick release slot to eliminate slipping; Self-starting for clean holes in thin materials; M35 cobalt HSS to cut stainless steel. The step drill bit is made with M35 cobalt. It is ideal for variety of materials from stainless steel, metal, plastic, fiberglass to wood. They also help to enlarge existing holes. M35 HSSCo is a high speed steel alloy made up of 5% cobalt. M35 is similar to M2, but with 5% cobalt added.
- The addition of cobalt increases heat resistance. It is widely used in metal manufacturing because of its ability to resist wear over conventional high speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time between tool changes. M35 is also less prone to chipping when used for interrupted cuts.

Fantastic! really this is the best step bit i have owned, went straight through a stainless steel counter for a sink, board out a larger hole on some motorcycle parts. I love quality tools and this definitely qualifies!
