Brad Point drill bits are widely used for drilling precise, clean holes in various materials, including wood, plastic, and metal. In addition to a sharp point that helps to center the bit accurately, these drill bits also have brad-style cutting edges that cut cleanly and reduce splintering. Brad Point drill bits can become dull over time and with regular use, affecting their ability to drill clean and precise holes. So, how to sharpen brad point drill bits?
Even the best brad point drill bits get dull. Sharpening Brad Point drill bits is a relatively straightforward process that can be accomplished with a bench grinder and other standard tools. Sharpening drill bits regularly increases their life and improves their performance, making it a valuable skill for DIY enthusiasts and professionals alike.
How To Sharpen Brad Point Drill Bits – Tools and Materials
Sharpening Brad Point drill bits requires the following tools and materials:
Bench grinder: A bench grinder is a primary tool used for sharpening the drill bit. It is essential to select a grinder with a well-balanced, adjustable-speed motor that is suitable for the size of the drill bit.
Dressing tool: A dressing tool is used to shape the grinding wheel and remove any build-up of abrasive particles that can clog the wheel and affect its performance.
Honing stone: A honing stone can further sharpen the drill bit after grinding, providing a smoother and more precise edge.
Protective gear: It is essential to wear eye and ear protection when using a bench grinder. Flying debris from the grinding process can cause eye damage, and the noise from the grinder can cause hearing damage if proper protection is not worn.
It is also a good idea to have a magnifying glass and a clean, flat surface to test the drill bit’s sharpness after grinding. Additionally, cloth or brush can remove debris or residue from the drill bit after sharpening.
How To Sharpen Brad Point Drill Bits – Preparations
Before beginning the sharpening process, it is vital to prepare the tools and materials properly.
Mounting the bench grinder: The bench grinder should be securely mounted to a flat, stable surface, such as a workbench or stand. The grinder should be level to ensure that the grinding wheel is in the correct position.
Selecting the correct grinding wheel: A fine-grit aluminum oxide or silicon carbide grinding wheel is best for sharpening Brad Point drill bits. The wheel should be in good condition and free from cracks or chips affecting its performance.
Adjusting the grinder speed: The speed of the grinder should be adjusted to suit the size of the drill bit being sharpened. A slower speed is best for smaller bits, while a faster speed can be used for larger bits.
Wearing protective gear: When using the bench grinder, it is essential to wear eye and ear protection, such as safety glasses and earplugs. It will help to protect against any flying debris or harmful noise levels.
You can sharpen your Brad Point drill bits with adequately prepared tools and materials.
Sharpening Process of Brad Point Drill Bits
1. Placing the Drill Bit on the Rest
– Place the drill bit on the rest of the bench grinder, with the cutting edge facing the grinding wheel.
– Make sure the drill bit is centered on the rest and secure.
2. Applying Light Pressure
– Apply light pressure to the drill bit as it rotates against the grinding wheel.
– Avoid applying too much pressure, as this can cause the drill bit to overheat and lose its temper.
3. Grinding the Tip until it is Sharp
– Move the drill bit back and forth across the grinding wheel, focusing on the tip and cutting edges.
– Continue grinding until the tip is sharp and the cutting edges are smooth and even.
4. Checking the Sharpness with a Magnifying Glass
– Remove the drill bit from the grinder and inspect it with a magnifying glass.
– Ensure that the tip is sharp and the cutting edges are smooth and even.
Using these steps, you can sharpen your Brad Point drill bit and restore its ability to drill precise, clean holes. Use a honing stone after sharpening the drill bit for an even finer edge.
