Product description
Type A and Type B Center Drills are precision-engineered tools designed for producing accurate center holes in workpieces prior to turning, grinding, or other machining processes. Made from high-speed steel (HSS) or solid carbide, these center drills ensure dimensional accuracy, stable centering, and smooth machining starts, particularly important in high-precision operations.
Type A Center Drills feature a single-angled point for producing standard center holes.
Type B Center Drills have an additional 60° countersink after the pilot tip, allowing for chamfering and better seating for lathe centers.
Both types are essential in lathe work, milling setups, and automated CNC operations, ensuring the cutting tool stays aligned and deflection is minimized.
Available in Type A and Type B: Choose based on your hole preparation requirements.
Precision Ground Tips: Delivers accurate centering and clean finishes.
Durable Material Options: Available in HSS for general purpose and carbide for high-hardness applications.
Reduced Breakage: Short, rigid design minimizes breakage during setup.
Smooth Chip Removal: Optimized flute design ensures smooth chip evacuation.
Versatile Compatibility: Usable in lathes, CNCs, drilling machines, and manual equipment.
Lathe Turning: Accurately positioning workpieces between centers.
Milling Prep Work: Creating pilot holes for high-speed drilling.
Grinding and Alignment: Ensuring axial symmetry before precision finishing.
Tool Setup: Common in jig fixtures, alignment setups, and high-volume CNC production.
