PRECISION HSS JOBBER LENGTH DRILLS, FRACTIONAL SIZE
- BLACK OXIDE, 118° PT. (R10) – ideal for portable or machine drilling in a board range of materials in the iron and steel families.
- BLACK OXIDE, 135° SPLIT PT. (R10B) – manufactured to National Aerospace standard 907, Type B. 135° split point is self-centering and reduces thrust. Ideal for portable or machine drilling of low tensile strength alloy materials, stainless steels, and other medium-duty applications.
- BLACK OXIDE, 135° SPLIT PT. (R10HD) – point is self-centering and reduces thrust. Originally designed to drill cotter pin holes. Heavy-duty construction to resist torsional strain when drilling high tensile strength steels.
