Hertel H95006221 Jobber Drill Bit Letter V 0.3770 in

Product Description

The HERTEL H95006221 is a letter-size V jobber drill bit engineered for heavy-duty holemaking in metal and general-purpose materials. Built from high speed steel with an oxide finish, this bit delivers consistent performance in production and maintenance drilling applications. The 137-degree split point geometry reduces walking at entry and lowers thrust requirements compared to conventional 118-degree points. At 0.3770 inches in decimal diameter and 5 inches overall length, this is a standard jobber-length tool suited for drill presses, CNC machines, and hand-held power drills. Two spiral flutes with a regular helix clear chips efficiently during through-hole and blind-hole operations.

This drill bit is intended for trade and industrial use where repeatable hole quality in the 0.3500 to 0.4000 inch diameter range is required. Typical applications include structural fabrication, HVAC rough-in drilling, plumbing rough-in, electrical conduit layout, and general metalworking. The heavy-duty grade designation makes it appropriate for higher feed rates and interrupted cuts. Right-hand cutting direction is standard for conventional spindle rotation. Three flats on the shank reduce slippage in standard drill chucks.

Key Features

• 137-degree split point reduces bit walking and entry thrust on hard or slick surfaces
• High speed steel construction with oxide coating for heat resistance and lubricity
• Heavy-duty grade rated for higher feed rates and interrupted cuts
• 2-flute regular spiral design promotes efficient chip evacuation
• Three flats on shank prevent chuck slippage during high-torque drilling
• Conforms to ANSI specification standards for consistent dimensional tolerancing

Compatibility

Designed as a standard jobber-length drill bit compatible with 3-jaw drill chucks and collet systems accepting a straight shank in the 0.3770 inch diameter range, suitable for drill presses, hand drills, and CNC drilling spindles.

Installation Notes

Install in a properly sized drill chuck and tighten securely using all three chuck key positions to engage the shank flats evenly. Disconnect power or engage the machine lockout before changing bits. Use appropriate cutting fluid or coolant for the workpiece material to extend bit life, even though this tool does not support coolant-through delivery. Confirm spindle speed and feed rate are appropriate for the workpiece material before beginning the cut.
