HARFINGTON Taper Chucking Reamer 1/2" M2 High Speed Steel Spiral Flutes Bridge Reamer Bit with 1/2" Shank for Metal Alloy Aluminum Wood Plastic Hole Reaming

M2 high-speed steel reaming tools offer excellent wear resistance, toughness and heat resistance for long-lasting use. With just a base substrate (no additional coating), suitable for a wide range of applications. Taper reamer bit can align and enlarge pre-drilled holes in preparation for attachment bolts.Tapered point reamer allows access to overlapping holes or precisely enlarges tapered holes, providing a smooth, precise finish. Spiral flutes help to effectively discharge chips when reaming, prevent chip clogging, reduce heat buildup, and improve cutting performance.Taper chucking reamers are used to precisely enlarge, align or finish existing holes in most metals, mild steel, mild steel, alloys, copper, wood and plastic prior to rivet or bolt installation. Can be widely used in automotive/truck/trailer industry, construction, bridge, and steel fabrication/installation.Machine reamer works with electric hand drills, lathes, drill presses and screw machines. Apply a cutting fluid or lubricant to the reamer and workpiece. It helps reduce friction and heat build-up, extending tool life and improving surface finish. Make sure the workpiece is securely clamped to minimize movement.Note: A reamer bit is not a drill bit, it just aligns or enlarges a pre-drilled hole. Before using our tapered reamers to enlarge the hole, a hole with a smaller diameter than the reamer should already exist. If chips begin to clog the reamer's chip flutes, cutting performance will be affected.
