Hertel 85703346 Jobber Drill Bit 3/64 Inch Hss 118 Deg

Product Description

The HERTEL 85703346 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high-speed steel (HSS) with a bright uncoated finish, this bit is sized at 3/64 inches (0.0469 inches decimal) and features a 118-degree standard point angle with web thinning for easier center starting and reduced thrust on entry. The straight-cylindrical shank seats securely in standard drill chucks, and the regular spiral flute promotes chip evacuation during through-hole drilling. Overall length is 1-3/4 inches with a 3/4-inch flute length. Machinists, maintenance technicians, and general trades use this size for pilot holes, light metalwork, and precision small-diameter drilling applications.

This bit is suited for bench drill presses, handheld electric drills, and CNC drill heads where a 3/64-inch straight-shank bit is required. Its general-purpose grade makes it appropriate for light-duty production runs or toolroom work where a small-diameter jobber bit is needed. The 2-flute spiral configuration handles a range of workpiece materials at standard speeds recommended for HSS tooling. Right-hand cut is the standard configuration for conventional drilling operations.

Key Features

• High-speed steel construction for durability across a range of workpiece materials
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Bright uncoated finish — no coating buildup that can affect tolerance on small-diameter bits
• Regular spiral flute with right-hand cut for conventional clockwise drilling
• Straight-cylindrical shank fits standard drill chucks without adapters
• 2-flute design promotes chip clearance in short, jobber-length drilling applications

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 3/64-inch straight-cylindrical shank.

Installation Notes

Install and remove drill bits only when the drill press or handheld drill is powered off and the chuck is fully stopped. Secure the straight shank fully into the chuck and tighten with a chuck key before operation. At 3/64 inches, this bit is fragile — use appropriate low feed pressure and spindle speeds recommended for HSS at this diameter to avoid breakage. A center punch mark on the workpiece helps prevent walking on entry.
