Hertel C.401.0048 Jobber Drill Bit 0.48 Mm Hss

Product Description

The HERTEL C.401.0048 is a high speed steel jobber drill bit ground to a 118-degree standard point angle. Designed for general-purpose drilling in a wide range of materials, this bit features a right-hand spiral flute configuration and a straight-cylindrical shank for direct chuck mounting. The bright, uncoated finish is standard for HSS jobber drills intended for versatile shop and field use. At 0.48 mm in diameter (0.0189 inches decimal equivalent) with an overall length of 22 mm, this is a precision micro-drill suited for fine work in metal, plastics, and similar substrates. Installation and use require a compatible precision drill chuck or collet rated for sub-millimeter tooling.

This bit is appropriate for benchtop drill press, CNC, or hand-drill applications where a small-diameter through-hole is required. General-purpose grade designation makes it a practical stock item for machine shops, maintenance technicians, electronics assembly, and tool rooms that regularly drill in the sub-0.5 mm range. The 5 mm flute length accommodates shallow drilling at this diameter without excessive deflection risk. Sold individually; minimum order quantity is 12 units.

Key Features

• 118-degree standard point angle for general-purpose drilling across common materials
• High speed steel construction provides adequate hardness and wear resistance for typical shop use
• Right-hand spiral flute promotes chip evacuation during drilling
• Straight-cylindrical shank fits standard precision collets and micro-drill chucks
• Bright, uncoated finish — no coating thickness to account for on tight-tolerance holes
• Two-flute geometry standard for jobber-length drills at this diameter

Compatibility

Designed as a general-purpose jobber drill for use in any drill press, CNC machining center, or hand tool equipped with a precision chuck or collet capable of holding a straight-cylindrical shank at 0.48 mm diameter.

Installation Notes

Micro-diameter drill bits in the sub-0.5 mm range require a precision collet or micro-drill chuck to minimize runout and prevent bit breakage. Ensure the spindle and workpiece are properly secured before operation; lateral force at this diameter will snap the bit. Feed rates and spindle speeds should follow published HSS cutting data for the specific workpiece material. Inspect the cutting edges under magnification before use and discard any bit showing visible chipping or deformation.
