Choosing the Right Drill Bit

The type of drill bit you select is critical for achieving the best results:

• For Woodworking: Use spade bits, brad point bits, or Forstner bits for clean cuts in wood.
• For Metalworking: High-speed steel (HSS) or cobalt bits are ideal for drilling into metal.
• Material Compatibility: Always match the drill bit to the material you’re working on to avoid damage to both the bit and the workpiece.

Operating Drill Presses

With your setup complete, it’s time to start drilling:

• Turning On the Machine: Ensure the drill bit is secure in the chuck, then toggle the power switch to turn on the drill press. Use the chuck key to make sure the drill bit is secure in the drill chuck.
• Lowering the Bit: Use the feed handle to lower the drill bit slowly and steadily into the material. Apply consistent pressure without forcing the bit. More pressure will not improve the results of the cutting tool.
• Drilling Holes: Keep an eye on the depth stop to ensure you don’t drill deeper than intended. Once the hole is drilled, gently raise the bit back to its starting position.
• Using a Center Punch: Before drilling, mark the spot with a centre punch to create a small indentation. This helps to guide the drill bit and prevent it from wandering off the mark. For cutting larger holes, especially in metal start with a smaller pilot hole.
• Backing Out Regularly: For deep holes, back the drill bit out periodically to remove chips and cool the bit. This practice reduces the risk of overheating and breaking the bit.
• Checking the Belt Tension: Periodically inspect and adjust the belt tension on the drill press. Proper belt tension ensures efficient power transmission and prolongs the life of the motor.
• Cooling Fluids: When drilling into metals or hard materials, use cutting or cooling fluids. This practice helps to reduce heat buildup, minimize bit wear, and ensure a cleaner cut.
• Using Drill Guides: For larger workpieces or challenging angles, use drill guides or jigs to maintain precision and accuracy during drilling.
• Emergency Procedures: Be familiar with procedures for stopping the drill press in case of an emergency. Knowing how to quickly shut off the machine can prevent accidents and injuries.
• Securing Long Workpieces: When working with extended materials, ensure they are adequately supported on both ends to prevent tipping or bending during drilling.
• Inspecting the Spindle: Regularly check the spindle for signs of wear or misalignment. A well-maintained spindle ensures better drilling accuracy and reduces machine vibration.
• Using Auxiliary Lighting: If your workspace lighting is insufficient, use additional task lighting to illuminate the drilling area clearly. Proper visibility is crucial for precision and safety.
• Cleaning the Drill Press: After each use, clean the drill press to remove dust, debris, and metal shavings. Regular cleaning prevents buildup and helps maintain the machine’s performance.
