Hertel H95006112 Jobber Drill Bit No 13 Hss 137 Deg

Product Description

The HERTEL H95006112 is a No. 13 wire-size jobber-length drill bit designed for general-purpose holemaking in metal and other materials. Built from high speed steel with an oxide finish, it carries a 137-degree split point that reduces walking and lowers the thrust needed to start a hole. The bit measures 3.5 inches overall with a 1.75-inch flute length, weighs 0.15 pounds, and runs a right-hand spiral flute pattern. It conforms to ANSI specifications and is rated as a heavy-duty grade tool suitable for production and maintenance drilling operations.

This bit is sized at 0.1850 inches (decimal) and falls within the 0.1500 to 0.2000 inch drill bit size range, placing it in common use for tapping prep, clearance holes, and light fabrication work. It is a standard jobber-series length, making it a practical choice for handheld drills, drill presses, and CNC drilling operations where moderate reach is needed. Machinists, maintenance technicians, HVAC installers, plumbers, and electricians reach for this size when drilling pilot or clearance holes through sheet metal, strut, pipe hangers, and structural steel.

Key Features

• 137-degree split point reduces drill walking and lowers feed pressure on entry
• High speed steel construction handles the heat generated in repetitive metal drilling
• Oxide finish provides mild lubricity and corrosion resistance during storage and use
• Right-hand, regular spiral flute evacuates chips efficiently from shallow to moderate depth holes
• Heavy-duty grade rating for demanding production and field service environments
• ANSI-conforming dimensions ensure compatibility with standard drill chucks and holders

Compatibility

Designed as an ANSI-standard jobber drill bit suitable for use in standard 3-jaw drill chucks and collet-style holders accepting round-shank bits in the 0.1500 to 0.2000 inch size range.

Installation Notes

Secure the bit firmly in a properly sized drill chuck before operation and verify the chuck key is removed before starting the spindle. Use cutting fluid or coolant when drilling ferrous metals to extend tool life, even though this bit does not support through-coolant. Wear appropriate PPE including eye protection when operating any rotary cutting tool. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
