Grewin HSSE A-type center drill

Product Introduction

The HSS Center Drill Type A is a commonly used hole-making tool, mainly applied for machining center holes on workpieces to provide accurate positioning and guidance in subsequent turning, grinding, or drilling operations. Its structure consists of a pilot tip and a tapered cutting section. Made of high-speed steel (HSS), it offers an excellent balance of hardness and toughness.

Product Features

1. High-quality material

   • Manufactured from high-speed steel (HSS), ensuring high hardness, wear resistance, and excellent cutting performance.

2. High machining accuracy

   • Ensures precise positioning of center holes and improves concentricity in subsequent operations.

3. Sharp and durable

   • Sharp cutting edge with high wear resistance for extended tool life.

4. Optimized structure

   • Type A center drills feature short tapers (60°, 75°, 90° available) suitable for different positioning requirements.

5. Wide versatility

   • Compatible with CNC machines, lathes, and drilling machines, offering broad adaptability.

Application Scenarios

1. Turning operations

   • For machining center holes on lathes to support the tailstock center, ensuring stability and concentricity during rotation.

2. Pre-drilling positioning

   • Used before drilling larger or deeper holes to prevent drill bit deviation.

3. Grinding or finishing reference

   • Serves as a reference hole for finishing or grinding operations to ensure accuracy.

4. Applicable materials

   • Suitable for steel, cast iron, copper, aluminum, and certain hard alloy materials.
