Draper HSS Long Drill Bit - 6.5 x 148mm

This Draper HSS Long Drill Bit is suitable for drilling holes in steel, cast iron, non-ferrous metals (like aluminum and brass), and plastics.

The 'Long' designation refers to the increased length of the drill bit (148mm), which provides greater reach for drilling deeper holes or accessing difficult-to-reach areas.

No, these HSS drill bits are specifically designed for metal and plastic. They are not suitable for use on concrete, brick, or other masonry materials.

Each pack contains five (5) Draper HSS Long Drill Bits.

HSS stands for High-Speed Steel, a type of tool steel used for drill bits and cutting tools due to its hardness, resistance to high temperatures, and durability.

After use, clean the bits thoroughly and apply a light coating of oil to prevent rust. Store them properly in a drill bit organizer or their original packaging.

Ensure the drill bit is sharp. If dull, consider replacing it. Check that you are using the correct drill speed and applying adequate pressure for the material. Verify the bit is spinning in the correct direction.

Reduce drill speed and apply steady, consistent pressure. Use a cutting lubricant or coolant, especially when drilling metals, to dissipate heat.

This can occur with excessive force, jamming, or drilling brittle materials at too high a speed. Ensure the hole is clear of debris and consider using a pilot hole if drilling through very thick material.

Ensure the drill chuck is tightened sufficiently. Clean both the drill chuck interior and the bit shank to remove any oil or debris that might cause slippage.
