Guhring 9005520037500 Screw Machine Drill Bit 0.1476 in

Product Description

The GUHRING 9005520037500 is a stub-length, screw machine drill bit designed for high-performance drilling in aluminum and other non-ferrous materials. Built from high-speed steel with a bright, uncoated finish, it measures 0.1476 inches (3.75 mm) in diameter and carries a 130-degree point angle with a parabolic flute geometry. The web-thinned, parallel-web construction reduces thrust and improves chip evacuation. At 2.0472 inches in overall length with a 0.7874-inch flute length, this bit fits standard straight-cylindrical shank toolholders and is sized to the DIN 1897 stub-length standard. It is a right-hand cut tool suited for production drilling environments.

This drill bit is intended for use in screw machine operations, CNC drilling centers, and bench drill press setups where a compact stub-length tool provides rigidity and reduced deflection. Its parabolic flute profile and web-thinned point are optimized for aluminum as the primary workpiece material, though the high-speed steel construction is also serviceable in plastics and soft metals. A maximum drilling depth of 0.5660 inches makes it appropriate for short, through-hole or blind-hole applications in production runs. Machinists, tool-and-die professionals, and precision-shop technicians are the typical end users.

Key Features

• 0.1476 inch (3.75 mm) diameter, DIN 1897 stub-length standard
• 130-degree split point angle reduces walking and entry burr
• Parabolic flute geometry promotes fast chip clearance in aluminum
• Web-thinned, parallel-web construction lowers drilling thrust
• Straight-cylindrical shank fits standard drill chucks and collets
• Bright, uncoated high-speed steel finish, right-hand cut

Compatibility

Designed as an OEM-style stub-length drill bit conforming to DIN 1897, compatible with standard straight-cylindrical shank toolholders and drill chucks accepting a 3.75 mm shank diameter. Primary workpiece material is aluminum per manufacturer specification.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals familiar with spindle speeds, feed rates, and chip load calculations for high-speed steel tooling. Secure the shank fully in the chuck or collet before operation and confirm runout is within acceptable tolerance. Do not exceed the maximum drilling depth of 0.5660 inches per pass without retracting to clear chips. Coolant-through is not supported on this tool; external flood or mist coolant is recommended when drilling aluminum at higher feed rates.
