Sgs 51027 Jobber Drill Bit No.27 0.144in Solid Carbide

Product Description

The SGS 51027 is a solid carbide jobber-length drill bit in wire gauge size No. 27, with a decimal diameter of 0.1440 inches (3.66 mm). Built to DIN 338 standards, it features a 118-degree faceted point and a regular spiral flute geometry for consistent chip evacuation in a wide range of materials. The micrograin carbide construction delivers hardness and wear resistance well beyond standard high-speed steel bits. It is designed for use in CNC machining centers, drill presses, and hand-held power tools where tight-tolerance holes and long tool life are required. Machinists, toolroom technicians, and precision fabricators are the primary installers of this bit.

The SGS 51027 is suited for drilling small-diameter holes in ferrous and non-ferrous metals, plastics, and composites. Its 2-flute, right-hand cut configuration and web-thinned tapered web reduce thrust load at entry, making it effective for through-holes and blind holes in production and maintenance machining environments. The 5xD flute-to-diameter ratio supports drilling depths up to 1.1093 inches in a single pass without pecking on most setups.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 118-degree faceted point for self-centering entry and reduced walking
• Web-thinned tapered web reduces axial thrust at drill entry
• Regular right-hand spiral flutes promote efficient chip evacuation
• Bright uncoated finish suitable for use with cutting fluids or dry
• Conforms to DIN 338 dimensional standard for consistent interchangeability

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard straight-shank drill chucks and collet systems accepting a 0.1440-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with carbide tooling handling. Secure the straight shank fully in a drill chuck or collet before starting the spindle. Carbide is brittle - avoid lateral loading, interrupted cuts without proper feed control, or dropping the bit on hard surfaces. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole tolerance.
