- Patented design features a razor sharp cutting rim to securely hold the edge of the bit while cutting.
- Equipped with a chisel edge to remove the material from the bottom of the hole to create a flat bottom.
- Titanium Nitride coated for extended bit life.
Multi-Spur Boring Bits
Uses: Used for drilling fast, accurate large diameter holes 1-1/2” to 2-9/16” for installing pipe, wire, conduit and insulation.
Features and Benefits:
- Removable coarse threaded screw quickly pulls the bit through the work leaving a smooth hole even in wet, gummy wood.
Hinge Master Boring Bits (Hinge Master)
Uses: Used for drilling smooth, flat-bottomed holes for concealed hinges. Best used in drill presses, drill stands and in drill guides.
Features and Benefits:
- Specially designed for installing style concealed hinges.
- Available with a Titanium Nitride coating or Carbide Tipped.
Masonry Drills
Specially designed to penetrate the porous material that makes up concrete, bricks and mortar. These bits have a micro-grain carbide tip that is designed to “chip” and “grind” out the hole.
Positive Carbide Tip – For use in a rotary drill, this tip comes to a single point and is strong enough for general masonry work.
Negative Carbide Tip – For use in a hammer drill (rotary and percussion, simultaneously), these tips are stronger and withstand the impact of a hammer drill for penetrating hard materials, like concrete.
Super Masonry Drills
Use: Used for drilling high bulk materials such as damp masonry work, brick, cement, tile, and cinder block.
Positive tip geometry for rotary drilling efficiency.
Features and Benefits:
- Wide spiral flutes efficiently remove dust and debris from the cutting area.
- Super Masonry drills are nickel/chrome plated which gives the drill an attractive finish and makes it rust resistant.
- Available in Jobber and 6" lengths.
- Also available in 13" and 20" lengths with wire installing hole. Features a hole near the tip of the drill that is used to pull the wire back through the hole after drilling.
Ultra Masonry Drills
Use: Used for drilling brick, stone, and concrete, ceramic, damp and dry masonry work and glass.
Negative carbide tip for rotary and percussion drilling.
Features and Benefits:
- Wide spiral flutes efficiently remove dust and debris from the cutting area.
- Available in Jobber and 6” lengths.
Glass and Tile Drills
Use: Used for drilling glass, tile or other hard, brittle materials.
Features and Benefits:
- Carbide spear point tip has uniquely sharpened edges for easy penetration in glass, mirror, and ceramic.
- Cuts perfectly round holes without chipping or breaking the material.
- Works best when used with a lubricant, even water.
Masonry Bit for Concrete Screws

- Carbide tipped for extended life.
- Available in two diameters - 5/32” and 3/16” to match the hole required for masonry screws.
Masonry screws have a special thread that actually cuts into the concrete and eliminates the need for anchors.
Specialty Bits
Specialty bits are designed to perform specific tasks. Some of the common bits include:
Carbon Steel Hole Saws
Use: Carbon Hole saws are designed to cut 3⁄4” to 3” holes in wood with a maximum depth of 1-1/8”. Uses include installing locksets or running pipe.
Features and Benefits:
- Available individually or with built-in arbor and pilot drill.
Bi-Metal Hole Saws
Use: Bi-Metal hole saws are designed to cut holes in metal and/or wood.
Features and Benefits:
- Bi-Metal steel combines two different types of steel that are sonically (and invisibly) welded together. This combination gives the hole saw flexibility and toughness to cut through metal, laminates or wood.
- Hole sizes range from 9/16” to 6” with a maximum depth of 1-3/4”.
- Available individually, with or without built-in arbor and pilot drill.
- Also available in multi size sets for Plumbers, Electricians and Contractors.
Circle Cutters
Use: Used to cut 1” to 6” holes in thin wood or plastic up to 1/2” thickness.
Features and Benefits:
- Reversible blade cuts inside or outside circle.
- Circle cutters should be used in a drill press.
Countersinks
Use: Used to make beveled, recessed holes for screw heads.
Features and Benefits:
- Countersink bits have flutes to cut out a seat for the head of a screw in soft metal, plastic or wood, rubber and other machinable materials.
- Also available in Titanium Nitride coating for extended service life.
Tapered Plug Cutters (Plug Kutter)
Use: Cuts a tapered plug that fits snugly in the hole to hide a screw head.
Features and Benefits:
- The Plug Kutter® shaves the sides of the plug as it cuts creating a tapered plug that gives an almost invisible line between the plug and the hole.
- Robust cutting prongs are extremely durable for cutting dense hardwoods.
- Titanium Nitride coating extends service life and reduces heat build-up, eliminating scorching.
Doweling Centers
Use: Used to ensure that two dowel holes are exactly aligned.
A dowel hole is drilled into one piece of wood. The doweling center is inserted into the drilled hole. The center point is then pressed against the second piece of wood. A mark is left where the hole should be drilled. The aligned pieces are then connected with the dowel.
Depth Stops
Use: Depth Stops make it easy to drill holes of precise depth. The stop slips onto the drill bit flute and can be secured at any desired point. When drilling, the stop will not allow the drill to go past a desired depth.
