Chatterless. Designed for fast shearing out. High speed steel with surface treatment (blackening).
High speed steel, general purpose, with 118-degree conventional point.
Type J, heavy duty, 135-degree split point (except sizes less than 1/16 inch). Cobalt drills display higher red hardness and are especially effective in drilling hard or abrasive materials.
High speed steel, general purpose, 118-degree conventional point. Use in left hand spindle rotation on screw machines and drill heads. Also use as screw extractor for drilling out broken studs or fasteners.
Heavy duty, 135-degree split point. Short flute length and overall length provide maximum rigidity drilling in stainless and other tough alloys, castings and forgings.
Use to chamfer, deburr, countersink and enlarge holes in sheet metal while providing smooth surface finish. Countersinks holes much smaller than other styles and should be operated at comparatively high speeds.
For tapping machining and stainless steels, aluminum, zinc and ductile material. Features hard to find over and under tolerances. Ground threads.
Testing has proven Blizzard Bit outperforms all other high speed 135-degree split point heavy duty drills! Use for either hand-held work or shop production. Proprietary steel keeps drills cooler than all others. Highest feeds and speeds. High speed pricing with cobalt performance. Special oxide and…
Each set has one each 1/4-, 3/8-,1/2-, 5/8- and 3/4-inch body diameter.
