Hertel C.401.0075 Jobber Drill 0.75 Mm Hss 118 Deg

Product Description

The HERTEL C.401.0075 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. It features a standard 118-degree point angle that provides reliable center-starting and clean hole entry across a wide range of workpiece materials. The bright, uncoated finish is suitable for most general drilling applications where specialized coatings are not required. At 0.75 mm in diameter (0.0295 inches decimal equivalent), this bit is sized for fine, small-diameter work. Machinists, toolroom technicians, and maintenance professionals typically use this bit in drill presses, CNC machines, and hand-held power tools.

This jobber drill bit is suited for light-duty and precision drilling tasks where small hole diameters are required. Common applications include pilot hole drilling, fixture and jig work, electronics assembly, and general metalworking. The two-flute spiral design promotes efficient chip evacuation in short-hole drilling scenarios. Its straight cylindrical shank allows seating in standard drill chucks without special toolholders.

Key Features

• 0.75 mm (0.0295 inch) diameter for fine, small-diameter hole work
• 118-degree standard point angle for reliable center-starting
• High speed steel construction for general-purpose durability
• Bright, uncoated finish suitable for most common drilling materials
• Two-flute right-hand spiral for efficient chip removal
• Straight cylindrical shank fits standard drill chucks

Compatibility

Designed as a general-purpose jobber drill bit compatible with standard drill chucks and collets accepting straight cylindrical shanks in the appropriate size range.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trained trade professionals. Secure the shank fully in the drill chuck before operation and verify concentricity to prevent bit deflection at small diameters. At 0.75 mm, the bit is fragile and requires reduced feed pressure and appropriate spindle speeds to avoid breakage. Always wear appropriate eye protection and secure the workpiece before drilling.
