Jerax tools M2 HSS 4-32mm Step Drill Bit – Heavy-Duty Hole Drilling

Overview

The Jerax tools M2 HSS 4-32mm Step Drill Bit is engineered to produce cleaner holes through extra thick materials. Crafted from M2 high speed steel, it combines durability with precision to support faster, smoother drilling in a range of common workshop materials.

Durability and Precision

• Increased alloy content provides wear resistance: 50% more Tungsten and 150% more Molybdenum contribute to longer edge life.
• Vacuum heat treatment and nitride surface hardening further enhance hardness and edge retention for repeated use.

Design for fast, visible drilling

• Polished steps and size highlights let you see the target hole size during drilling, reducing interruptions.
• High-accuracy CNC processing and refined design deliver easy, fast, and clean cuts compared with typical step bits.

Versatility and compatibility

This single bit handles a wide range of materials including stainless steel, hardened metal, mild steel, galvanized steel, aluminum, copper, plastic, and wood. It is capable of drilling through thick sections, up to 12 ga / 2.7 mm in stainless steel, with proper pressure.

Convenient size options

• Four marked hole sizes are built in: 8 mm, 16 mm, 24 mm, and 32 mm, allowing you to drill multiple hole sizes without changing bits.

What you get in use

Ideal for workshops, home projects, and light fabrication, this bit provides a reliable option when precision and speed matter. For best results, use steady feeds and lubrication as needed, and follow manufacturer guidance for your material.

Care and tips

• Keep the bit cool with light lubrication to extend life.
• Apply steady, even pressure and let the bit do the work for clean holes.
