Hertel 85703726 41/64" HSS Bright 118° Jobber Drill Bit

This is a new Hertel 41/64" (0.640625") high speed steel (HSS) jobber length twist drill bit, part number 85703726, featuring a bright (uncoated) finish and a conventional 118-degree included point angle with a standard chisel edge. The bright finish indicates no post-grind coating or heat treatment, making it well-suited for drilling general-purpose materials including mild steel, aluminum, brass, and plastics where a cost-effective HSS solution is acceptable. As a jobber length drill, the flute-to-body proportions follow standard jobber geometry, providing a balance of rigidity and reach appropriate for use in drill presses, knee mills, and hand-held power drills with a suitable chuck capacity. The 41/64" diameter is a common fractional size used in production environments for clearance holes, pre-drill operations before reaming, and through-hole applications across a wide range of ferrous and non-ferrous workpieces.
