Metal Working and Multi-Purpose Drill Bits are the most commonly used drill bits for a wide variety of applications. Metalworkers and construction professionals use a variety of high speed steel, cobalt steel, carbide-tipped steel and solid carbide bits designed for general purpose or heavy duty usage.

Mechanics length drill bits increase your productivity by eliminating slippage and reducing work stoppage for drill or battery changes

High Quality, Heavy Duty HSS Titanium drill bits. Great economical but durable bit for general purpose applications. Super hard Titanium nitride surface treatment. A much faster chip flow and decreases horsepower requirements

Large Size High Speed Drill Bits 1/2" up to 1-1/2"

SOLID CARBIDE Drills. Used in Aerospace and fantastic on non-ferrous alloys, cast iron, plastics, aluminium, and highly abrasive materials. Super high performance drilling. Exotic Metals.

Left-hand bit

Left-hand bits are almost always twist bits and are primarily used in the repetition engineering industry on screw machines or drilling heads. Left-handed drills allow a machining operation to continue when the spindle either cannot be reversed or where the design of the machine makes it more efficient to run left-handed. With the increased use of the more versatile CNC machines, their usage is less common than when specialized machines were required for machining tasks.

Drill Bits with the left-hand twist may also be used as an aid in the removal of common right-hand screws. Since the rotation of the drill bit is reversed, it would loosen the screw. Using this drill bit to drill into the damaged screw head will usually remove the screw, providing the bit "grabs" the damaged material successfully.

Maintenance Reamers

Used in steel erection, automotive, truck and trailer manufacturing and repair
Quickly aligns structural steel
Cuts stainless steel and tough alloys
Deburs welded & punched holes
Ideal for maintenance and repair

Shank diameter is the same as the reamer diameter.
Sizes 0.652 and 0.776 are specifically for shoulder bolts used on truck frames.

Carbide Burs

Our burs are made with one thing in mind… To make your work easier! Double cut burs are designed to remove metal faster and gives a coarser finish. The Single cut bur is made for a more gradual material removal and finer finishes

Carbide burs are harder and stay sharper longer than high-speed steel. Burs with head dia. larger than shank dia. have a steel shank and carbide head. All others are solid carbide. Approx. overall length is 1 1/2" for 3/32" shank tools; 1 1/2"-2 1/8" for 1/8" shank; 2" for 3/16" shank; and 2"-3 3/8" for 1/4" shank.

Double End Drill Bits are used for drilling thin sheet metal like truck and auto bodies. These drill bits are popular for pop rivet drilling applications. High Speed Steel, Surface Treated, 135° Split Point.

Hex Shank Fractional Size Drill Bits are designed for cordless power screwdrivers. They perform well under a wide variety of normal conditions. High Speed Steel – Surface Treated – 118° Point

Screw Machine Length Drill Bits were developed primarily for use in screw machines and manufactured to NAS 907 type C Aircraft specifications. The shorter length of these drills offer increased rigidity for strength, making them ideal for medium duty portable or machine drilling in low alloys or stainless steels. High Speed Steel, Surface Treated, 135° Split Point

Reduced Shank Drill Bits are made of premium grade steel. Mechanic's length are longer than screw machine length, yet shorter than jobber length. The special 3-flat shank provides a positive grip in cordless, keyless and conventional power tools.

Long Taper Length drill bits are designed for general purpose drilling in situations where extra reach is needed. High Speed Steel, Bright Finish, 118° Point.

Masonry Drill Bits- Regular helix with wide flutes improve dust removal. For best performance, use slow speed and apply enough feed pressure to keep the drill cutting. These bits are recommended use in brick, concrete and sandstone. 118° point, Black oxide

Carbide hammer Bits

Carbide Hammer Drill Bits are designed for quick drilling in masonry, rock, concrete, brick and artificial stone. They should only be used with heavy duty power tools using either the A-Taper 1:20 or B-Taper. Can also be used in combination with corresponding adapters.

Carbide Hammer Spline Shank bits are used for quick drilling in masonry, rock, concrete, brick and artificial stone. Their special design generates less vibration and reduces friction and heat.

Carbide Hammer Straight Shank bits for use in quick drilling of masonry, rock, concrete, brick and artificial stone. For use in all drills with a standard chuck.

Brad Point Drill Bits are used to drill clean, flat-bottomed holes in wood. For precision wood cutting in popular sizes: 1/8”, 3/16”, 1/4”, 5/16”, 3/8”, 7/16”, 1/2”

Jobbers’ Drill Bits

The industry standard, jobbers’ drills are the most widely used. These drill bits are designed to perform general purpose and heavy duty drilling with both portable and machine tools. Our Jobbers’-Length drill bits are available in high speed steel, cobalt steel, and carbide-tipped high speed steel. We also have special coatings available to increase the productivity and life of your bits.

HX-18 Wire Size Jobber Drill Bits for lower thrust requirements, improved cutting action and reduce walking. Heavier web provides greater tool strength. Longer length of the secondary cutting edge of split point forms a more manageable chip. 135° split point

R18 Wire Size Drill Bits perform satisfactorily under a variety of normal conditions. They are designed to work in a broad range of materials using both machine and portable drilling. High speed Steel, Surface Treated 118° Point.

Metric Size Drill Bits are designed to perform satisfactorily under a wide variety of normal conditions. They will work in a broad range of materials and in both machine and portable drilling. • High Speed Steel, Surface Treated, 118° Point.
