The Irwin Cordless Multi-Purpose Drill Bit in 10mm diameter with 140mm overall length is designed for heavy-duty drilling applications requiring substantial hole diameter. This large size is ideal for major fixings, larger coach bolts, and demanding construction applications across multiple materials. Specifically designed for cordless, low-speed multi-purpose drilling, it offers around 10% extra battery life per charge.
Featuring a precision four-facet ground carbide tip, this drill bit ensures lower drilling pressure and superior centring despite the substantial diameter, making large-hole drilling more manageable. This 10mm variant excels at combined drilling tasks, allowing you to drill through wood directly into brickwork with a single bit, perfect for major installations.
