Hoffman Diamond Products manufactures many types of mining bits for coring shallow holes. The types of bits include surface set, impregnated, polycrystalline diamond (PCD) and carbide. They also manufacture core catchers and reaming shells. Surface set bits are available in semi-round, step, spiral, and face discharge configurations. Their geotechnical bits drill for a variety of formations from extremely abrasive to non-abrasive and faulted to solid. Bit are specifically design to drill in many rock types including hard shale, limestone, granite, serpentine, dolomite, basalt, diorite, gabbro, gneiss, chert, rhyolite, quartzite, and sandstone.
Hoffman Diamond Products manufactures saw blades and thin wall coring bits for the sawing and drilling of concrete, asphalt, granite, marble, brick, block, tile and other construction materials. Saw blades sizes can range from 6’ to 60” in diameter and coring bits sizes can range from 1/2” to 48” in diameter. Hoffman excels in small to medium production runs offering customers the capability rapid prototyping of diamond tools for sawing or drilling required by unique one of kind construction or architectural projects.
Hoffman Diamond Products manufacturing an array of diamond metal bonded tools for the sawing, drilling, reaming and grinding of glass, fused silica, fiberglass, ferrites, alumina, zirconium, quartz, porcelain, sapphire, and many other ceramics throughout industry. Products include large diameter blades, grinding pads for Blanchard grinding, and close tolerance coring bits.
FEATURING OUR NEW HIGH PERFORMANCE 50MM U-NOTCHED SEGMENTS.
Today after more than 105 years, Hoffman Diamond is proud to remain a privately held, and American owned company. Hoffman give you over 100 years of experience in the design and manufacture of diamond tools to solve your toughest problems.
The construction industry demands a variety of bonds for diamond sawing and drilling tools. Diamond saw blades and bits cut or drill concrete, asphalt, brick, block, tile, granite and marble. Diamond tools have proven to be the most cost effective way to penetrate these materials.
The Grizzly Line is Hoffman's trademark for the construction supply and rental industries blades. These wet and dry blades are for smaller, hand-held saws and grinders and are designed for equipment operating at less than 18 horsepower.
Cured Concrete Blade Specifications
OPTIONAL VERTICAL DROP SEGMENTS
Vertical Drop Segments (VDS) or kickers are used
on cured concrete, asphalt and green concrete blades
to retard core undercutting. VDS is available in 3
levels of undercut protection: Standard Protection
available at no charge; Extra Protection or Maximum
Protection available at a slight nominal charge.

Grinding Heads & Wheels
Hoffman's Heavy Duty and Premium Blades and Grinding Heads are top-of-the-line production tools. These tools are specifically designed and manufactured for the professional who demands precision cutting and grinding with a long life expectancy.
Designed for deep hole drilling where it is important and economical to keep the bit in the hole as long as possible. Hoffman diamond has developed a new series of matrices and manufacturing techniques to produce a new series of impregnated bits. This series includes types designed to drill a complete range of rock conditions.
CONDOR SURFACE SERIES SET
Tungsten carbide Casing Shoes for softer formations.
Sawtooth - Aggressive cutting speeds in softer formations.
Crackerjack - Moderate cutting speeds in medium formations.
Popcorn - Universal application for soft to medium formations.
Casing Shoes where diamonds are needed:
Impregnated -Universal application for hard to very hard formation.
Surface Set - Moderate cutting speeds in hard formations.
In keeping with Hoffman's strategy to be at the cutting edge of diamond bit and tool technology, the application of polycrystalline diamond compacts was an early priority. PCD tools are generally
run on drills with higher torque and lower RPM than Surface Set or Impregnated Bits
The Hoffman Sales and Technical Personnel will be pleased to work with you in producing full hole and coring products that will meet your particular needs
