Ingco Step Drill Bit 4 22mm - AKSDS42203

Summary

The Ingco Step Drill Bit 4-22mm (AKSDS04221) creates multiple hole diameters in sheet metal and plastic using one bit. High-speed steel construction maintains edge integrity under high RPM. Titanium coating reduces friction during continuous drilling operations.

Key Features

1. Titanium Coating: Reduces friction and heat buildup during high-speed metal drilling. Extends bit life during heavy use.
2. HSS 4341 Construction: High-speed steel 4341 core provides necessary hardness for industrial tasks. Resists snapping under heavy torque.
3. 10-Step Sizing: Incremental diameters from 4mm to 22mm in 2mm steps. Eliminates the need for multiple bits.
4. Two-fluted Design: Clears chips and debris faster than single-flute alternatives. Prevents clogging in humid conditions.
5. Round Shank: Fits standard 13mm or 10mm keyed and keyless chucks. Provides a secure grip in drills.
