## Description

TEMO M35 Cobalt Spiral Flute Step Drill, 12 Size From 3/16 Inch To 7/8 Inch, 1/4 Inch Hex Shank

Review: So my husband needed this for work It came fast as heck! He said it gets the job done so what more can you say it’s as described and his input is the piece is decently priced!
Review: Drilled threw my stainless steel sink so I could install a pull up sprayer. Make sure to use and keep adding a generous amount of cutting fluid and enough pressure that you can see the shaving as it cuts. The hole was neat and clean when you go threw each of the steps to the hole size you want. I used a spring punch a few times to mark a very small indent then a small drill bit (cheap titanium coated drill bit, and that is all it could do) to make a little bigger starting point for the TEMO M35 step drill. Eventually i will order a smaller TEMO cobalt step drill.

- 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.
