View Product Description

2 straight flutes carbide step drill with for mold steel making

Introduction:

High-precision multi-diameter drilling tools designed for carbon steel, stainless steel, and hardened alloys. Featuring solid carbide construction and straight-flute geometry, these step drills deliver burr-free edges, exceptional rigidity, and extended tool life in demanding industrial applications.

Features:

Straight Flute Design – Eliminates chip entanglement (ideal for sticky steels)

Multi-Diameter Steps – Drill and chamfer in one operation (e.g., 3–5 steps per tool)

Ultra-Fine Carbide Substrate – Optimized for HRC 45+ materials

Wear-Resistant Coating – TiAlN/TiCN coatings reduce friction and heat buildup

Rigid Shank – Precision-ground for <0.01mm runout

Performance Advantages:

50% faster than conventional twist drills in stacked/stainless steel

No secondary deburring required (clean hole edges)

Consistent accuracy across all step diameters (±0.02mm)

Typical Applications:

• Automotive (body panels, brackets)

• Sheet metal fabrication (electrical enclosures, HVAC)

• Machinery (bearing seats, hydraulic ports)
