Key Features & Benefits
- Reduced 12.7mm 3-flat shank — fits standard 13mm drill chucks while allowing larger cutting diameters, with three flats preventing slip under heavy load.
- Patented step tip design — reduces heat buildup, prevents jamming, and eliminates the need for pilot holes in steel and stainless.
- Black oxide treatment — enhances lubricant hold and ensures smooth chip flow for cleaner cutting and longer tool life.
- High-speed steel construction — durable HSS body designed to drill hundreds of holes in half the time of conventional bits.
- Burr-free, centred holes — the step tip produces perfectly centred holes without jagged edges, reducing post-drilling cleanup.
- Australian first — the Onsite+ reduced shank range is a market first, engineered specifically for the demands of Australian metalworkers.
When to Use This Drill Bit
The 9LMST145R in 14.5mm is designed for metalworkers and fabricators who need to drill larger-diameter holes using a standard 13mm drill chuck or drill press. The reduced 3-flat shank provides maximum grip and torque transfer while allowing the full cutting diameter of 14.5mm. For smaller diameters (3–13mm), the ¼″ hex shank step tip bits are more convenient for cordless impact driver use.
