Guhring 9024630049800 Stub Drill Bit 0.196 in Carbide

Product Description

The GUHRING 9024630049800 is a stub-length (screw machine length) solid carbide drill bit designed for precision hole-making in demanding shop and field applications. Built to DIN 6539 standards, this bit features a 118-degree faceted point angle with web thinning to reduce thrust and improve centering accuracy. The 2-flute regular spiral geometry promotes efficient chip evacuation. At 0.196 inches (wire size No. 9) in diameter with a straight-cylindrical shank, it installs directly into standard drill chucks and collet holders without adapters. This bit is suited for machinists, maintenance technicians, and toolroom professionals who need consistent, repeatable performance in tight-tolerance drilling operations.

This drill bit is rated for general-purpose drilling with aluminum listed as the primary workpiece material, though its solid carbide K40 grade construction supports use in a range of non-ferrous and engineered materials. The stub-length body keeps the drill rigid and reduces deflection in short-reach setups, making it a practical choice for CNC machining centers, drill presses, and manual lathes. The coated finish provides additional surface hardness and lubricity at the cutting edge. Maximum drilling depth is 0.730 inches per pass.

Key Features

• DIN 6539 standard, Series 2463 solid carbide construction in K40 material grade
• 118-degree faceted point with web thinning for accurate entry and reduced thrust
• Stub (screw machine) length body at 2.441 inches overall for high rigidity and low deflection
• Straight-cylindrical shank at 4.98 mm diameter for compatibility with standard chucks and collets
• Regular 2-flute spiral geometry with 1.024-inch flute length for efficient chip clearance
• Coated finish for extended edge life in general-purpose applications

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard drill chucks and collet systems accepting a straight-cylindrical shank in the 4.98 mm range, conforming to DIN 6539 specifications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the spindle is fully powered down and at a complete stop before changing or seating the bit in the chuck or collet. Verify chuck runout is within acceptable tolerance before drilling to avoid premature edge wear on carbide tooling. Carbide bits are brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper feed adjustment, or dropping the tool on hard surfaces.
