When to choose an installation bit

Choose this type when you need to drill large through holes quickly, drill deeper holes or repeatedly prepare multiple service penetrations. The replaceable threaded tip helps guide the bit into the cut and makes it easier to drill through the material without applying excessive pressure to the drill.

What you will find in this category

Here you will find installation bits, replacement threaded tips and extensions for installation bits. The extensions are useful when drilling in hard-to-reach areas or where the standard tool length is not sufficient.

Do you need a clean flat-bottomed hole rather than a through hole?

For precise blind holes with a flat bottom in natural wood, Forstner Bits DIN 7483 G, Not Toothed or Forstner Bits with Teeth DIN 7483 G are a better choice. If you are drilling hardwood, chipboard or coated boards, take a look at TCT Boring Bits.
