Guhring 9024630019300 Carbide Stub Drill Bit 0.076in

Product Description

The GUHRING 9024630019300 is a solid carbide stub-length drill bit designed for precision drilling in demanding shop and production environments. Machined to DIN 6539 standards, this bit features a 118-degree faceted point with web thinning for clean entry and reduced thrust. The 0.076-inch (wire size 48) diameter and straight-cylindrical shank suit it for use in standard drill chucks and collet holders. With a 3xD flute-to-diameter ratio and spiral flutes, it provides reliable chip evacuation in short-hole applications. Licensed machinists, tool-and-die technicians, and CNC operators typically specify this bit for tight-tolerance work where carbide rigidity and edge retention matter.

This bit is rated for general-purpose drilling with a primary workpiece material designation of aluminum, though its solid carbide construction supports use in a broad range of non-ferrous and engineered materials. Its stub-length geometry limits deflection and maximizes rigidity in setups where a shorter reach is preferred over extended reach. It is well suited for screw machine, CNC turret, and bench drill press applications requiring repeatable hole placement and diameter accuracy within a tolerance of +0.000 to -0.010 mm.

Key Features

• Solid carbide construction in material grade K40 for edge retention and rigidity
• 118-degree faceted point with web thinning for reduced entry thrust and clean hole starts
• Stub-length (screw machine) geometry: 1.496 inches overall length, 0.472-inch flute length
• Right-hand spiral flutes with 3xD ratio for efficient chip evacuation
• Straight-cylindrical shank compatible with standard chucks and collets
• Conforms to DIN 6539 specification for consistent dimensional quality

Compatibility

Designed as an OEM-style replacement or production drill bit for stub-length applications requiring a 0.076-inch (wire size 48) diameter hole in aluminum and similar materials, conforming to DIN 6539 and GUHRING Series 2463.

Installation Notes

Installation and use should be performed by qualified machinists or CNC technicians familiar with carbide tooling. Secure the shank fully in a properly sized collet or drill chuck before operation, and verify runout is within acceptable limits, as carbide is brittle and sensitive to side loading. Do not exceed the recommended maximum drilling depth of 0.359 inches without retracting to clear chips. Inspect the cutting edges before each use, as carbide tips can micro-chip if dropped or improperly stored.
