Hertel C.402.0370 Jobber Drill Bit 3.70mm Hss

Product Description

The HERTEL C.402.0370 is a high speed steel jobber-length drill bit ground to a 3.70 mm (0.1457 inch) diameter with a standard 118-degree split-point angle. The two-flute spiral design clears chips efficiently during through-hole and blind-hole drilling operations. An oxide finish reduces friction and provides light corrosion resistance during use. At 76 mm overall length with a 48 mm flute length, this bit fits standard drill chucks with a straight cylindrical shank and is well suited to general-purpose metalworking applications in shop or field environments.

This drill bit is rated for general-purpose use and falls within the 3.00 mm to 4.00 mm diameter size range. It is commonly used in metal fabrication shops, maintenance and repair operations, and manufacturing environments where consistent, repeatable hole quality is required. The right-hand cutting direction is compatible with standard drill presses, hand drills, and CNC drilling setups. It is sold individually per package with a minimum order quantity of 12 units.

Key Features

• 3.70 mm (0.1457 inch) diameter for precise hole sizing
• 118-degree standard point angle for general-purpose drilling
• High speed steel construction withstands moderate heat and wear
• Oxide coating reduces friction and light corrosion during use
• Two-flute spiral design promotes efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber drill bit compatible with standard drill presses, hand drills, and CNC drilling equipment that accept straight cylindrical shank bits in the 3.00 mm to 4.00 mm diameter range.

Installation Notes

Secure the shank fully in the drill chuck before operation and verify chuck key removal prior to powering the tool. Use appropriate feeds and speeds for the material being drilled to avoid premature wear or bit breakage. Eye protection and chip guarding are standard requirements when drilling metal. Cutting fluid is recommended for extended production runs to prolong bit life.
