RUKO KEB-HSS-TiAlN broca de coroa 43,0 mm de diâmetro de corte, 30 mm de profundidade de corte, haste Weldon 19 mm

This RUKO annular cutter stands out with its TiAlN coating, which delivers up to four times the tool life of uncoated HSS cutters. Designed for magnetic drilling machines and pillar drills, it produces precise, burr-free holes in steel, stainless steel, cast iron, and non-ferrous metals.

Highlights

• TiAlN coating for enhanced hardness, wear resistance, and heat resistance
• Hollow design removes a core, reducing cutting force and power consumption
• Optimized geometry ensures efficient chip evacuation
• Weldon shank for secure clamping in standard holders

In daily use

The cutter's 43.0 mm diameter and 30 mm cutting depth handle thick materials in a single pass. External cooling is recommended to maximize tool life. A core ejector pin is required but not included.
