60° Carbide Center Drill Bit Double Head Drill Bit For Hardened Steel

60° carbide center drill bit for hardened steel double heads

Introduction:

The double-head carbide center drill bit is a high-precision, heavy-duty cutting tool designed for spot drilling, centering, and chamfering hardened steels, alloy steels, and other tough metals. Featuring two interchangeable cutting ends made of solid tungsten carbide, it offers twice the tool life and exceptional durability in demanding machining applications.

Features:

1. Double-Head Design (2-in-1 Functionality)

• Two usable ends – Doubles tool lifespan before replacement.

• Saves cost & downtime – Flip the drill when one end wears out.

2. Solid Tungsten Carbide Construction

• Extreme hardness (HRA 90+) – Ideal for hardened steel (HRC 50+), stainless steel, and titanium alloys.

• Superior wear resistance – Outlasts HSS and cobalt center drills.

3. Precision Ground Geometry

• 60° or 90° point angle – Ensures accurate centering and chamfering.

• Self-centering tip – Reduces bit walking for perfectly aligned holes.

4. Heavy-Duty Performance

✔ CNC machining & lathe work
✔ Spot drilling before tapping or deep-hole drilling
✔ Hardened steel, tool steels, and superalloys

Recommended Specifications

• Material: Solid tungsten carbide (optional TiAlN coating).

• Shank Type: Straight shank (3mm–12mm).

• Point Angle: 60° (standard), 90° (for wider chamfers).
