915 Generation 50Pcs Drillforce Tools M35 Cobalt Drill Bit SetHss-Co Drill Set 1-3MmFor Drilling On Hardened Steel Cast Iron&Stainless Steel

M35 Cobalt Steel - Manufactured from M35 cobalt steel with molybdenum and cobalt added to creates a hardened alloy measuring hardness up to 67 for much faster and extra life span with up to when compared with an average HSS drill bit
No Center Punch Needed - the 135° quick-cut points are self-centering and penetrate quickly with less pressure Will not "" or "wander"
For Stainless Steel - Particularly successful in through hard metals such as stainless steel and cast iron although they can be used for softer materials too Not for hardened steel high carbon steel Try to adjust the RPM when it fails to penetrate
50pcs Set - The set includes 50pcs of metric M35 cobalt steel twist drill bits 1mm 15mm 2mm 25mm 3mm 10pcs of each size
Color gold
Material Cobalt steel alloy
Cobalt drill bits are not made of pure cobalt rather a steel alloy with certain percent cobalt The 5-percent alloy is known as M35 grade The cobalt increases the strength of the steel and makes it more heat-resistant
For Drilling Stainless Steel
This M35 cobalt steel drill bits are particularly successful in through hard metals such as stainless steel and cast iron although they can be used for softer materials too
135 Degree Split Point
The flater the drill the smaller the chip width This means less force required to remove metal compared with lower angles like 90° and 118° This is important on hard stuff because your power requirements are already more than mild steel so making the chip load less helps It also reduces heat since less surface area is generating the cut
Not Suggested for Hardened Steel High Carbon Steel and Steels Blended with Impurities
Cooling Required
use with cooling to prolong the working life of the drill bits and to avoid overheating and breakage
About Breakage
be careful when you drill holes with shese -like small bits They're more likely to than larger ones
