The irw10502527 is a 5mm hss cobalt drill bit supplied in a pack of 10, representing one of the most commonly used sizes in metalworking applications. This diameter is perfect for drilling stainless steel and high alloy steels for a wide range of fixings, brackets, and structural work. The 5mm size is frequently specified in mechanical assembly, fabrication projects, and general maintenance tasks. Engineered with 5% cobalt content, this drill bit offers exceptional resistance to heat and abrasion, maintaining its cutting performance far longer than standard hss alternatives. The heavy-duty web construction ensures maximum strength and rigidity, reducing deflection and the risk of breakage during demanding applications. The 135 split point starts drilling immediately upon contact, eliminating bit walk and ensuring precise hole placement every time.
