SDS-max® Hammer Carbide
SDS-max® Rotary Hammer Bits
Bosch carbide rotary hammer bits feature tips that
stay sharper longer and deliver more holes within
their ANSI specification than competitors' bits. Also,
Bosch shafts wear at a much slower rate than most
others and can take more abuse because of Bosch's
technologically advanced conditioning process.
• Manufactured to ANSI standards, Bosch bits also meet and exceed ISO
(International Standards Organization) standards. 98% of the carbide tips
are molded to the specific ANSI size. Only 2% (specials) of all bit diameters
are ground to size
• SDS-max® rotary hammer bits not only fit Bosch SDS-max® hammers, but
also competitive SDS-max® drive hammers and Hilti hammers using TE-Y
and TE-FY shanks

SDS-max® Thru-hole Rotary
Hammer Bits
One-piece thru-hole bits are designed for fast
working without the need to change shanks. The
all-in-one core with SDS-max® shank transmits power directly to the end of the
bit. Additionally, thru-hole bits are economical due to their long life.
