## Overview

The M35 5% Cobalt Metric Drill Bits Set features 19 high-performance bits crafted from hardened M35 cobalt steel alloy with molybdenum, delivering up to 67 Rockwell hardness. Its precision 135° split point and gold oxide surface ensure efficient chip removal and reduced walking, making it ideal for drilling stainless steel, cast iron, and other hard metals. Packaged in a durable case, this set offers professional-grade durability—lasting 12 times longer than standard HSS bits—perfect for demanding industrial and DIY projects.

## Description

Suitable for drilling Stainless Steel,Hard Metals,Aluminum,Copper,Plastic and Hardwood. The 3 steps design makes it accurately centered for woodworking jobs that require precision drilling. Also, the cobalt-containing design makes it perform even better in hardwood drilling. Controling the drill speed from 200 to 1000 RPM would make it easier for you to drill holes on stainless steel. A high RPM does not improve drilling efficiency, but rather increases the heat between the bit and the workpiece, which may cause the bit to soften and the workpiece to harden. Drill diameter≤5mm，RPM（1000~700） 5-10mm，RPM（700~350） 10-15mm，RPM（350~200） Using cutting fluid will make the bit last longer. Add stainless steel tapping oil or engine oil to prevent the stainless steel from overheating and forming a very hard oxide layer. It also works adding some vinegar,soy sauce or water if you don't have engine oil.

Review: very nice product
Review: I made my mounting rack for my solar panels out of used steal pipe, and I had to drill quite a few holes for mounting these panels. The piping was quite hard and I bought five drill bits, so as to make sure I wouldn't run out. To my surprise the drill bits held up really well and I was able to drill all the holes with just one bit. I did pre-drill the holes with a center drill, but that was all I used, and of course some lubricant. I never thought that I could drill these many holes without wearing out the drill bit. Quite amazing.

## Questions & Answers

**Q: I ordered this set but it came as a much cheaper set in a weak, brittle case. Is this what is being sent now, or was this just a shipping mistake?**
A: Mine came in a clear plastic case with a black plastic divider section.   Not the greatest however I needed the bits to work, not the case.

**Q: I want to drill 8 to 10 holes through large, stainless steel hinges (3mm thick).Could I do the job with these drills?**
A: Probably but you will need the right cutting fluid .
I did not use this bits on SS yet.
Thank you
GOOGLE:
"What can you use to cut stainless steel fluid?
As a manufacturer of metal processing oil, we recommend MORESCO BS-6M soluble cutting fluid, MORESCO BS-9 soluble cutting oil. WILL CM-128 semi-synthetic cutting oil, WILL CH-370 semi-synthetic cutting fluid. These cutting oils are especially good on stainless steel, and provide excellent performances during machining."

**Q: Is this suitable for the soft metal in jewelry?**
A: yes, any metal

**Q: Where are they made?**
A: Unfortunately I could not find a country of manufacture this company.   They are inexpensive bits, and I've had good luck with them.

*by A***R on 27 January 2024*

A hardened piece of steel that broke several conventional bits did not stop these drills. Amazing difference from normal drill bits. Use caution; they will snap if driven too hard / fast. Use lubricant and go slow...they work very well.
