Guhring 9005520047600 Screw Machine Drill Bit 3/16in Hss

Product Description

The GUHRING 9005520047600 is a screw machine length (stub) drill bit designed for high-throughput metal drilling in production and maintenance environments. Built from high-speed steel (HSS) with a bright uncoated finish, it features a 3/16-inch diameter, a 130-degree cone-relief point, and a parabolic flute geometry that promotes fast chip evacuation and reduces heat buildup at the cutting edge. The web-thinned tip lowers entry resistance on harder workpiece materials. At 2-7/16 inches overall length with a 1-1/32-inch flute, this stub-length bit provides added rigidity compared to jobber-length equivalents, making it well-suited for drill press and CNC applications where deflection control matters.

This bit is intended for drilling steel, aluminum, and non-ferrous metals. The stub-length format is a standard choice in screw machine operations, short-hole drilling fixtures, and any setup where a shorter, stiffer bit improves hole location accuracy. The straight cylindrical shank accepts standard drill chucks without modification, and the right-hand cutting direction suits conventional drill press and lathe tailstock use. Machinists, toolroom technicians, and maintenance mechanics working in production or fabrication shops are the primary users. It conforms to DIN 1897 specification for stub-length drills.

Key Features

• HSS construction with bright uncoated finish suitable for general-purpose metal cutting
• 130-degree cone-relief point angle for aggressive entry on steel and non-ferrous materials
• Parabolic fast-spiral flute design promotes efficient chip removal and reduces chip packing
• Web-thinned tip reduces thrust force required at drill entry
• Stub length (DIN 1897 Series 552) provides greater rigidity than jobber-length bits
• Straight cylindrical shank fits standard drill chucks; no adapter required

Compatibility

Designed as an OEM-style replacement or direct-use stub drill conforming to DIN 1897 standards, compatible with any drill press, CNC machining center, or lathe tailstock chuck accepting a 3/16-inch straight shank. Primary workpiece materials are steel, aluminum, and non-ferrous metals.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with drill press or CNC operation. Secure the shank fully in the chuck and verify runout before drilling. Always power down and lock out the machine before changing tooling. Cutting fluid or coolant is recommended for steel applications to extend tool life, even though this bit does not feature through-coolant capability.
