Center drills are specialized cutting tools designed to create precise conical holes in workpieces, primarily for lathe centers or other machining operations requiring accurate alignment. These versatile tools combine drilling and countersinking into a single operation, ensuring clean, burr-free holes with excellent concentricity.
Ideal for metalworking, woodworking, and CNC machining, center drills are essential for:
Creating center holes for lathe work
Starting holes for drilling operations to prevent bit wandering
Chamfering and deburring holes
Aligning parts in fixtures and jigs
Engineered to produce exact 60° center holes for lathe centers
Prevents drill bit wandering for straighter, more accurate holes
Combines drilling and countersinking in one tool
Reduces tool changes, saving time and improving efficiency
Made from high-speed steel (HSS) or carbide for extended tool life
Resistant to wear, heat, and deformation
Suitable for metals (steel, aluminum, brass), plastics, and wood
Used in lathes, milling machines, drill presses, and CNC machines
Available in various diameters and lengths to suit different workpiece thicknesses
Most common type with a pilot drill and 60° countersink
Used for general-purpose centering in machining
Features a larger 60° chamfer for deeper centering
Ideal for heavy-duty applications
Extra-hard carbide tips for machining hardened metals
Longer tool life in high-speed operations
Reinforced design for tough materials like stainless steel and cast iron
Center drills are classified by number sizes (e.g., #0, #1, #2, #3, #4, #5) or metric dimensions.
| Size | Drill Diameter (mm/in) | Countersink Angle | Shank Diameter (mm/in) |
|---|---|---|---|
| #0 | 1.0 mm (0.039") | 60° | 2.5 mm (0.098") |
| #1 | 1.8 mm (0.071") | 60° | 3.0 mm (0.118") |
| #2 | 2.5 mm (0.098") | 60° | 4.0 mm (0.157") |
| #3 | 3.2 mm (0.126") | 60° | 5.0 mm (0.197") |
| #4 | 4.5 mm (0.177") | 60° | 6.0 mm (0.236") |
| #5 | 6.0 mm (0.236") | 60° | 8.0 mm (0.315") |
Custom sizes and angles available upon request.
Clamp the material firmly in a vise or lathe chuck to prevent movement.
Use lower RPMs for harder materials (e.g., steel) and higher RPMs for softer materials (e.g., aluminum).
Position the drill tip at the desired center point.
Feed the drill smoothly into the workpiece without forcing it.
Retract the drill occasionally to remove metal chips and prevent clogging.
Ensure the hole is clean, burr-free, and properly centered.
Lubrication: Use cutting fluid for metals to reduce heat and extend tool life.
Storage: Keep drills in a dry, organized case to prevent damage.
Sharpening: Regrind dull drills using a specialized tool grinder.
Avoid Overheating: Excessive heat can weaken the drill-use proper speeds and feeds.
