Feature

●HSS (M35) material: more robust than HSS 6542, very suitable for processing stainless steel, but of course also for processing plastics, wood, sheet metal, etc.
●TiAlN coating: high hardness, high wear resistance, high thermal stability, etc. Please note that the coating is not disposable and is very scratch-resistant due to the excellent process.
●Straight groove drill: the straight groove drill has higher machining accuracy and lower cutting force, suitable for processing materials with high hardness
●10 mm triangular shank: the straight 10 mm triangular shaft does not break so easily compared to the easy to install hex shank and is suitable for any drill chuck
●Class 15 (4-32 mm): pre-drilling, re-drilling and deburring of 4-32 mm can be done with just one drill, eliminating the frequent change of drills


Description

The ITEMPESTI M35 step drill bits are made of high-quality M35 cobalt steel with a hardness of 66-69 HRC (Rockwell hardness); the surface is coated with TiAlN, which increases heat and corrosion resistance, it is worth noting that this coating is definitely not cheap and disposable! It is very durable. Suitable for drilling and reaming metal and stainless steel.
