HTT offers a comprehensive range of cutting and drilling tools
organized into eight core product lines, each engineered to
deliver reliable performance across diverse materials and
applications:

Hammer Drill Bits
Available in SDS-plus and SDS-max shank systems, featuring
2-cutter, 4-cutter, and 6-cutter configurations. Designed for
concrete, masonry, and reinforced substrates, with specialized
designs including Quick-Stop and multi-flute geometries for
optimized debris removal and drilling speed.

Masonry & Multi-Purpose Drill Bits
Covering cylindrical, hex, and tri-flat shank types in both
DIN and ANSI standards. Includes specialized solutions for
natural stone, granite, glass, and tile, as well as
multi-purpose bits that perform across mixed materials.

Core Drill Bits
Diamond and TCT core drills for wet and dry cutting
applications. Technologies include laser-welded diamond
segments, sintered diamond bonds, and specialized porcelain
and hole-saw designs for demanding materials.

Metal Drill Bits
HSS twist drill bits in M2 and M35 (cobalt) grades, with
TiN-coated options for extended tool life. Available in
cylindrical, DIN hex, and Morse taper shanks, offered
individually or in assembled sets.

Carbide Tools
Tungsten carbide rotary burs in multiple geometries for
material removal, deburring, and surface finishing on metals
and composites.

Wood Drill Bits
Flat wood bits, brad point drills, ship auger bits,
countersinks, and plug cutters. Includes nail-cutting augers
and SDS-plus compatible variants for heavy-duty framing
applications.

Router Bits & Sets
TCT (tungsten carbide tipped) router bits with bearing-guided
profiles including bead, ogee, roundover, rabbeting, and crown
molding designs. Available individually and in multi-piece
sets.

Saw Blades
Diamond saw blades manufactured via sintering, hot pressing,
and silver brazing processes. Applications range from tile and
ceramic cutting to brick, block, and wall chasing, plus TCT
brush cutter blades for outdoor power equipment.
