For tapping machining and stainless steels, aluminum, zinc and ductile material. Features hard to find over and under tolerances. Ground threads.
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, 135-degree self-centering split point. Oxide finish creates porous layer to hold cutting oil to provide abrasion resistance and improved chip flow.
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.
High speed steel, general purpose, with 118-degree conventional point.
High speed steel, bright finish, general purpose, 118-degree conventional point. Better chip ejection in low carbon, nonferrous materials.
For tapping machining and stainless steels, aluminum, zinc and ductile material. Features hard to find over and under tolerances. Ground threads.
Because of short overall and flute lengths, drills are recommended for boring mills, screw machines, lathes or anywhere short projection is required. With 118-degree point.
Cobalt drills display higher red hardness and are especiallyeffective in drilling hard or abrasive materials. All bits except sizes 61 to 80 have 135-degree self-centering split point.
High speed steel, general purpose. With 135-degree self-centering split point. Drills marked with an asterisk (*) do not have a split point.
High speed steel, right hand. Standard included angle 60 degrees.
High speed steel, bright finish. General purpose, 118-degree conventional point.
