Draper HSS Drill Bit - 9/64"

This 9/64" HSS drill bit is suitable for wood, plastics, soft metals (like aluminum and brass), and mild steel.

While HSS bits can cut mild steel, they are generally not recommended for hardened steel without specialized techniques or coatings. For hardened steel, consider carbide-tipped or cobalt drill bits.

After use, clear any debris from the flutes using a brush or compressed air. Store in a dry environment to prevent corrosion.

These are international standards that ensure the dimensional accuracy, material quality, and performance characteristics of twist drill bits, guaranteeing a high level of precision and reliability.

Yes, this drill bit is compatible with any standard drill, including cordless drills, provided the chuck can securely grip the 9/64" shank.

The frequency of sharpening depends on usage. For light DIY tasks, it may last a long time. For frequent professional use, sharpening may be needed periodically to maintain optimal cutting performance.

Ensure the drill is rotating at the correct speed for the material. Check if the bit is dull and requires sharpening. Apply adequate pressure and consider using a cutting fluid for metals.

Verify the drill bit is securely tightened in the chuck. Ensure the drill is held perfectly perpendicular to the material surface. Check for excessive runout in the drill chuck.

Reduce drilling speed and apply more frequent pauses for cooling. Use cutting fluid or coolant, especially when drilling harder materials or for extended periods.

For wood and plastics, consider using a backing board to support the material where the bit exits. Reduce the drill speed and ensure the cutting edge is sharp.
