Their easy to use machines sharpen standard twist bits, masonry bits and carbide bits in minutes, extending the life of your drilling arsenal. With models designed for DIY and professional shops, Drill Doctor helps you cut cleaner holes while saving money.

What types of drill bits can Drill Doctor sharpen?

Drill Doctor sharpeners can sharpen a wide range of bit types depending on the model:

• High-speed steel (HSS) and cobalt bits, commonly used for metal and wood

• TiN‑coated bits (though coating may be lost during sharpening)

• Some models (e.g. 750X and SB) support masonry and carbide-tipped bits
  Most models handle standard twist bits from around 3/32″ to ½″, with higher-end versions (like 750X) supporting up to ¾″ and harder bits.

How do I sharpen a drill bit using a Drill Doctor?

The basic process is as follows:

• Secure the bit in the chuck and align it using the alignment port

• Set the desired point angle (e.g. 118° for general use or 135° for split-point bits)

• Insert the chuck into the sharpening port, and rotate it gently against the diamond wheel

• Polishing rotations (around 20–40 turns) refine the edge

• Inspect visually and test on scrap material as needed
  This replicates factory sharpening geometry in seconds.

What maintenance and warranty support is available?

Drill Doctor offers a 3-year limited warranty with authorized distributors (e.g. Drill Doctor UK) including repairs and spare parts access. Maintenance tips include:

• Cleaning the diamond wheel or chuck to remove metal swarf

• Replacing the wheel when performance declines

• Keeping the alignment port free of debris for accuracy
  Regular upkeep extends tool life and sharpening consistency.
