Hertel C.402.0325 Jobber Drill 3.25mm Hss 118 Deg

Product Description

The HERTEL C.402.0325 is a high speed steel jobber-length drill bit ground to a 118-degree standard point angle and finished with an oxide coating. Sized at 3.25 mm (0.1280 inches) in diameter, it runs a 41 mm flute length within a 70 mm overall length. The straight-cylindrical shank seats securely in standard drill chucks, and the two-flute right-hand spiral geometry clears chips efficiently during through-hole drilling. The oxide finish provides a moderate level of surface hardness and heat resistance suited to general-purpose drilling in common metals and plastics.

This drill bit is intended for general-purpose production and maintenance drilling in shop, field, and light industrial settings. Machinists, maintenance technicians, and fabricators use jobber-length bits like this one for standard-depth holes in mild steel, aluminum, brass, and similar materials. The 3.25 mm diameter falls within the 3.00 mm to 4.00 mm size range, making it a common selection for tapping preparation, clearance holes, and light-duty layout work on manual or CNC drill presses and handheld power drills.

Key Features

• 3.25 mm (0.1280 inch) diameter for precise hole sizing in the 3.00-4.00 mm range
• 118-degree standard point angle for general-purpose entry into metals and plastics
• High speed steel construction with oxide coating for moderate heat and wear resistance
• Two-flute right-hand spiral geometry promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard 3-jaw drill chucks
• 70 mm overall length with 41 mm flute length — jobber proportions suitable for most general drilling depths

Compatibility

Designed as a general-purpose jobber drill for use in standard drill chucks accepting straight-cylindrical shanks across manual drill presses, benchtop machines, and handheld power drills.

Installation Notes

Secure the straight shank fully into the chuck and verify concentricity before drilling. Use appropriate cutting fluid or coolant when drilling steel to extend tool life, even though this bit does not support coolant-through delivery. Ensure workpieces are clamped or fixtured before applying feed pressure to prevent bit walking on entry. Inspect the cutting edges for wear or chipping after extended use, as a dull 118-degree point will cause heat buildup and oversized holes.
