| Reduced 3-Flatted Shank Drill Bits |
 |
| Ideal for drilling in tough, high tensile strength materials. They are precision ground for a high degree of concentricity between shank and body diameter. Shank has triangular-shaped design. |
|
| Taper Shank Drill Bits |
 |
| Made to fit Morse tapered holders. Designed to perform in a broad range of materials in the iron and steel families. |
|
| Concrete Screw Anchor Bits |
 |
| Designed for drilling in brick, concrete, and sandstone. They are larger than the nominal drill sizes to provide clearance for installation of anchor screws. |
|
| Screw Machine Length Drill Bits |
 |
| The shorter flute and overall length increase the rigidity, resulting in less deflection, better hole accuracy, and longer tool life. Sizes smaller than 1/16 and larger than 1/2 have the 118º standard point. |
|
| Taper Length Drill Bits |
 |
| Designed for general purpose drilling of iron and steel families in cases where a length longer than Jobber Length is required. |
|
| 6 Inch Aircraft Extension Drill Bits |
 |
| Ideal for drilling in mild steels where extra length for reach is required. They have a black oxide surface treatment that is abrasion resistant, reduces chip welding and improves chip flow. Manufactured to National Aerospace Standard 907. |
|
| Straight Shank Drill Bits |
 |
| Designed for general purpose drilling of iron and steel families in cases where extra long length is required. |
|
| 12 Inch Aircraft Extension |
 |
| Ideal for drilling in mild steels where extra length for reach is required. They have a black oxide surface treatment that is abrasion resistant, reduces chip welding and improves chip flow. Manufactured to National Aerospace Standard 907. |
|
| Masonry Drill Bits |
 |
| Designed for drilling in brick, concrete, and sandstone. |
|
| Core Drill Bits |
 |
| Used to size or enlarge a hole previously drilled, cored, punched, or other pre-formed holes. Not designed to drill from solid. |
|
| Reduced Shank Drill Bits |
 |
| Ideal for drilling in tough, high tensile strength materials. They are precision ground for a high degree of concentricity between shank and body diameter. |
|
| Jobber Length Drill Bits |
 |
| Jobber-length drills are most common type of drill. The length of the flutes is ten times the diameter of the drill. |
|
| Die Drills |
 |
| Designed for drilling hardened steels in the range of 45-65 Rc. Run at 75 to 100 surface feet per minute with steady hand feed. Note: Sizes under 11/64" are solid carbide spade construction. |
|
| Standard Length Drill Bits |
 |
| These are made for solid carbide and are designed for drilling abrasive materials or in high temperature applications. Used on cast iron, high silicon aluminum, copper, plastics, bronze, hard rubber, plexiglass, and other similar materials. |
