Drill bit set faster tools 02-12-2230 Ø4–32 mm, 3 pcs
Conical HSS drill bits with titanium nitride coating from faster tools, set of three sizes covering Ø4–32 mm. The set includes three stepped bits designed to enlarge holes progressively and provide longer tool life due to the TiN surface treatment.
The titanium nitride (TiN) coating increases surface hardness and reduces wear, extending the service life of the HSS stepped drill bits. The conical (stepped) geometry enables drilling and controlled hole enlargement in a single tool, reducing tool changes. The set contains three complementary size ranges to cover common sheet metal and thin material hole patterns.
Secure the workpiece and select an appropriate rotation speed for HSS with TiN coating; start at a moderate speed and increase if necessary. Center-punch the starting point, then drill using light steady pressure, allowing the stepped bit to progress through each diameter. Retract periodically to remove chips and avoid overheating. Use cutting fluid when working with tougher materials to prolong tool life.
Use appropriate personal protective equipment, clamp the workpiece, and select speeds and feed rates suitable for HSS TiN-coated tools. Avoid excessive heat buildup to preserve the coating and cutting edge.
