Hertel C.E96.S29-3 Jobber Drill Bit Set 29pc Hss Tin

Product Description

The HERTEL C.E96.S29-3 is a 29-piece jobber length drill bit set manufactured from high-speed steel with a titanium nitride (TiN) coating. The TiN coating increases surface hardness and reduces friction, extending tool life in production and maintenance drilling applications. Bit sizes range from 1/16 inch through 1/2 inch in 1/64-inch step increments, covering the full wire gauge range needed for most general metalworking, fabrication, and mechanical service tasks. The 135-degree split-point tip reduces walking on entry and requires less thrust than a conventional 118-degree point. Bits are stored in a metal case for organization and jobsite transport. This set is suited for use by HVAC technicians, plumbers, electricians, and general maintenance mechanics.

This drill bit set is designed for jobber-length drilling in metal, plastics, and similar materials encountered in trade and light industrial work. The 1/16-inch to 1/2-inch size range covers the common fastener clearance, anchor, and pilot hole sizes used in residential and commercial installation work. The metal storage case keeps bits indexed by size, reducing time searching for the correct bit on a multi-task service call. The set is appropriate for use with standard corded or cordless drills and drill presses operating within the speed ranges appropriate for high-speed steel tooling.

Key Features

• 29-piece set covering 1/16 inch to 1/2 inch in 1/64-inch increments
• 135-degree split-point tip for reduced walking and lower entry thrust
• High-speed steel construction for durability across metal and plastic substrates
• Titanium nitride coating increases surface hardness and extends bit life
• Metal storage case included for organized, indexed bit storage
• Coolant-through design not required, suitable for standard handheld and bench drill applications

Compatibility

Designed as a general-purpose jobber length drill bit set compatible with standard 3-jaw keyed and keyless drill chucks accepting shanks up to 1/2 inch, as used in corded drills, cordless drills, and drill presses common to HVAC, plumbing, electrical, and mechanical service trades.

Installation Notes

Drill bits should be installed in a properly tightened chuck before operation. Match spindle speed to the material being drilled — high-speed steel bits require lower RPM in harder metals to prevent overheating and premature edge failure. Secure the workpiece before drilling to prevent rotation. Inspect bits for chipping or dulling before each use and replace worn bits to maintain hole quality and reduce the risk of breakage.
