Bits (Chisels)
Bit types include:
- Spade - provides flat finish for concrete or edging in asphalt or dirt
- Flat tip - allows direction control or finer edge finish
- Point - general breaking
- Stake driver - drives concrete form stakes
- Scabbler - finishes surface smooth or for cleaning prior to bonding
- Flex chisel - flexible metal blade (attached to shank with bolts) for tile removal and scraping
- Bushing tool - multiple carbide points for cleaning up seams and knocking down rough spots in concrete
Chisel sharpening:
Chisels may be sharpened in a shop or with an angle grinder with grinding disc. After sharpening, they must then be heat treated to restore the integrity of the steel before use. As an alternative, Hilti also manufacturers self sharpening polygon and flat chisels in SDS-max, TE-S, and 1-1/8" Hex connection ends.

Famous quotes containing the word bits:
“On their slag heap, these children
Wear skins peeped through by bones and spectacles of steel
With mended glass, like bottle bits in slag.”
—Stephen Spender (1909–1995)
