IRWIN INDUSTRIAL TOOL CO - ACH 91140 5/8 Reduced Shank Drill Bit

This 5/8 reduced shank drill bit from IRWIN INDUSTRIAL TOOL CO - ACH delivers reliable, high-speed performance for professional power tool users. Designed for clean, consistent holes in metal and wood, the 91140 bit is made to resist wear while maintaining cutting precision. The reduced shank allows secure fitment in standard drill chucks while offering the shear strength and accuracy expected from a utility-grade HSS drilling solution.

Drills And Accessories

The 91140 drill bit integrates seamlessly with handheld and benchtop drills. Its reduced shank dimension ensures broad compatibility with common chucks, reducing the need for adapters. Professionals appreciate the balance of rigidity and cutting speed that enables fast, repeatable results across fabrication, maintenance, and shop tasks.

Grinders And Saws Compatibility

While this product is a drill bit rather than a grinding or sawing accessory, specifying compatibility with site tooling is key. The high-speed steel construction resists thermal stress encountered when drilling tough alloys, and the geometry supports use before or after grinding operations and alongside saw cutting workflows in automotive and metalworking environments.

Professional Power Tools For Automotive Use

Built for professional power tools and heavy duty automotive power tools workflows, the IRWIN 91140 supports garage and shop applications where durability matters. Its reduced shank profile is particularly useful when larger bit diameters must be driven by standard chucks on popular automotive drills. The bit performs well on steel panels, brackets, and general fabrication materials commonly found in automotive repair and restoration.

Specifications are clear: 5/8 diameter with a reduced shank to fit standard chucks, high-speed steel construction, and geometry tuned for clean chip evacuation. Packaging and labeling reflect professional retail standards suitable for trade counters and service departments.
