Guhring 9005490014000 Drill Bit Size 54 Hss 130 Degree

Product Description

The GUHRING 9005490014000 is a jobber length drill bit designed for precision drilling in a range of materials. Built from high speed steel with a bright, uncoated finish, this Series 549 bit features a parabolic flute geometry and a 130-degree point angle that supports fast chip evacuation and accurate entry. The bit measures 0.0551 inches in diameter (wire gauge size 54) with an overall length of 1-9/16 inches and a straight-cylindrical shank. The web-thinned, tapered web design reduces thrust and improves centering at the start of the cut. This is a right-hand-cut, two-flute bit built to DIN 338 standards and rated as a high performance grade by the manufacturer.

This drill bit is suited for drilling aluminum and other non-ferrous and ferrous materials in light to medium production environments. The parabolic flute profile moves chips out of the hole efficiently, making it a practical choice for applications where clean holes and consistent diameter tolerance are required. Typical users include machinists, maintenance technicians, and fabrication professionals working with small-diameter hole requirements on manual or CNC drilling equipment. The maximum drilling depth is 0.626 inches (15.90 mm), and the flute length is 23/32 inches (18.26 mm).

Key Features

• Wire gauge size 54 diameter at 0.0551 inches for tight-tolerance small-hole work
• 130-degree point angle for reduced thrust and self-centering entry
• Parabolic flute geometry promotes efficient chip evacuation
• Web-thinned, tapered web reduces cutting force and heat buildup
• High speed steel construction with bright, uncoated finish
• Conforms to DIN 338 standard for jobber length drill bits

Compatibility

Designed as a DIN 338 jobber length drill bit suitable for use in standard drill chucks accepting straight-cylindrical shanks. Primary workpiece material classifications include aluminum (K, N, P material codes per the manufacturer). No coolant-through capability; intended for dry or externally cooled drilling operations.

Installation Notes

This bit is installed and used by machinists and maintenance technicians on drill presses, hand drills, or CNC equipment with compatible chuck capacity. Ensure the chuck is fully tightened and the workpiece is securely clamped before drilling. At this diameter, excessive feed force or off-axis pressure can cause bit breakage; use a slow, steady feed rate. Inspect the cutting edges before each use and replace the bit if chipping or wear is visible.
