Stewart Fastener T27 Bright Finish Steel Jobber Drill Bit 7

Product Description

The STEWART FASTENER T27 is a size 7 bright finish jobber-length drill bit built from Triumph steel for general-purpose drilling applications. The bright finish indicates an uncoated surface, making this bit well suited for drilling into softer materials where coating adhesion is not a primary concern. Jobber length refers to the standard flute-to-overall-length ratio that balances reach and rigidity, a format preferred by tradespeople for most everyday hole-making tasks. This bit is appropriate for use with standard drill presses, hand drills, and magnetic base drills common to fabrication shops, mechanical rooms, and job sites.

Size 7 jobber-length bits are commonly used in electrical, plumbing, HVAC, and general mechanical trades where precise hole sizing is required for tapping, wire routing, or fastener clearance. The Triumph steel construction provides the hardness needed for repetitive use in steel plate, structural members, and similar ferrous stock. This bit is intended for installation and service professionals who require reliable, consistent performance in production or field drilling scenarios.

Key Features

• Size 7 designation for precise hole sizing suited to tapping and fastener clearance work
• Bright finish uncoated surface appropriate for softer ferrous and non-ferrous materials
• Triumph steel construction provides hardness and wear resistance for repetitive drilling
• Jobber length geometry balances flute depth and rigidity for general-purpose use
• 118-degree point angle is the standard geometry for versatile material compatibility

Compatibility

Designed as a standard jobber-length drill bit compatible with conventional drill chucks accepting the appropriate shank diameter for a size 7 bit, suitable for use in hand drills, drill presses, and magnetic base drills.

Installation Notes

Drill bit installation and use should follow standard machining safety practices. Secure the workpiece before drilling and ensure the bit is fully seated and tightened in the chuck before operation. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the bit for wear or damage before each use and replace if the cutting edges are visibly degraded.
