Hertel 61698536 15/16 in HSS Oxide 118° Screw Machine Drill Bit

This is a new Hertel 61698536 screw machine length (stub) drill bit in 15/16 in diameter, manufactured in the USA from high-speed steel (HSS) with a black oxide surface treatment for improved lubricity and corrosion resistance. The 118° conventional split-point geometry is ground for general-purpose drilling in steel, cast iron, aluminum, and other common engineering materials. Screw machine length drills feature a shorter flute and overall length compared to jobber drills, providing increased rigidity and reduced deflection — well-suited for drill press, turret lathe, screw machine, and CNC lathe applications where a standard-length drill would chatter or wander. The straight shank accepts standard drill chucks and is engraved "HERTEL 15/16 HS USA," confirming brand, size, material, and domestic manufacture directly on the tool.
