Hertel C.401.0045 Jobber Drill Bit 0.45 Mm Hss

Product Description

The HERTEL C.401.0045 is a high speed steel jobber-length drill bit ground to a standard 118-degree split-free point. At 0.45 mm (0.0177 decimal inch) in diameter, this bit is designed for precision drilling in small-diameter applications where controlled feed and tight tolerances are required. The bright, uncoated finish is standard for general-purpose HSS tooling and is suitable for use in a wide range of ferrous and non-ferrous materials. With a two-flute spiral configuration and straight-cylindrical shank, it seats reliably in standard collet chucks and keyless drill chucks. Overall length is 22 mm with a 5 mm flute length.

This drill bit is well suited for light machining, tool-and-die work, electronics assembly, and precision fabrication applications where sub-millimeter hole sizes are required. The right-hand cutting direction is compatible with standard clockwise-rotating spindles found on benchtop drill presses, CNC machining centers, and handheld precision drills. General-purpose grade HSS construction makes it a practical choice for production shops and maintenance environments alike.

Key Features

• 0.45 mm diameter with 0.0177 decimal inch equivalent for cross-reference
• 118-degree standard point angle for general-purpose drilling
• High speed steel construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish — no coating buildup to affect small-hole dimensional accuracy
• Two-flute spiral design promotes chip evacuation in short flute-length applications
• Straight-cylindrical shank fits standard collet chucks and keyless chuck systems

Compatibility

Designed for use in any standard drill press, CNC machining center, or precision handheld drill equipped with a collet or keyless chuck capable of holding a straight-cylindrical shank in the sub-millimeter range.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician familiar with small-diameter drill bit handling. Always ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use the lowest practical feed rate for sub-millimeter diameters to avoid bit deflection or breakage. Secure the workpiece firmly before drilling to prevent wandering on the initial entry cut.
