Built from M2 high-speed steel with five tapped spiral flutes, the bit is designed to clear debris and hold an edge long enough for common site tasks. It is best for users who value fit and function - particularly in bridge construction, steel erection, or trailer maintenance - and need a solid reamer that fits a 1\/2in non-slip chuck.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize and purpose:\u003c\/strong\u003e Cuts and smooths predrilled holes to 13\/16in so fasteners and rivets seat precisely without play.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Made from M2 high-speed steel for resistance to heat and wear during routine metal and wood reaming tasks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute design:\u003c\/strong\u003e Five long tapped right-hand spiral flutes move chips away from the cutting edge for cleaner holes and reduced clogging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank and grip:\u003c\/strong\u003e The 1\/2in round shank with three-sided flats gives a firmer chuck grip and reduces slippage under load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in safety features:\u003c\/strong\u003e A tapered point and safe stop help the bit enter imperfect holes and prevent over-reaming when the correct size is reached.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatility:\u003c\/strong\u003e Suitable for steel, aluminum, brass, copper, plastic and PVC where accurate hole size and alignment matter.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis reamer is aimed at contractors, metal fabricators, and maintenance technicians who need a rugged tool to align or enlarge holes on steel structures, conduit runs, and vehicle frames.
