Guhring 9014520049000 4.9mm Carbide Jobber Drill Bit

Product Description

The GUHRING 9014520049000 is a solid carbide jobber length drill bit designed for precision hole-making in demanding machining applications. Built from submicron carbide with a bright uncoated finish, it measures 4.9 mm (0.1929 inches) in diameter with a 62 mm (2.44 inches) overall length and a 35 mm (1.38 inches) flute length. The 150-degree drill point angle and web-thinned, tapered web geometry promote self-centering entry and reduce thrust force. Three spiral flutes provide efficient chip evacuation. This bit conforms to DIN 6539 and suits machinists and tool-and-die professionals working on precision components.

This drill bit is suited for use in machining centers, CNC lathes, and manual drill presses where tight tolerances and clean hole entry are required. The 5xD flute-to-diameter ratio and right-hand spiral cut make it appropriate for drilling through ferrous and non-ferrous metals in production and job-shop environments. The straight-cylindrical shank fits standard collets and drill chucks. Maximum drilling depth is 27.65 mm (1.09 inches). Typical users include machinists, tool-and-die makers, and precision fabricators working in Series 1452 tooling setups.

Key Features

• Solid submicron carbide construction for wear resistance and dimensional stability
• 150-degree point angle with web-thinned, tapered web for self-centering performance
• Three-flute spiral design for improved chip evacuation and feed rates
• Bright uncoated finish compatible with a wide range of cutting fluids and workpiece materials
• Right-hand cut with regular spiral type for standard CNC and manual machine setups
• Conforms to DIN 6539 specification for consistent dimensional quality

Compatibility

Designed as a DIN 6539 Series 1452 jobber length drill bit in the 4.00 mm to 5.00 mm diameter range, fitting standard straight-cylindrical collets and drill chucks sized for 0.1929-inch shank diameters.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with carbide tooling. Secure the straight-cylindrical shank fully in a collet or drill chuck before running the spindle. Carbide tooling is brittle — avoid impact, side loading, or interrupted cuts beyond the tool's rated capacity. Always confirm spindle speed and feed rate are appropriate for the workpiece material before beginning the cut.
