Product Specifications:
Left‑hand spindles are uncommon, but when your CNC lathe or special machine runs counter‑clockwise, you need a center drill that matches the rotation. This HSSE R‑type center drill is engineered specifically for left‑hand applications, with a 5mm tip and 60° cone that meets DIN333. The protective radius prevents over‑entry and protects the workpiece shoulder – critical when you've already finish‑machined the outer diameter.
What sets this tool apart is its shorter relief length: only 1.52mm of straight relief after the 13.2mm cone, totaling 14.72mm per end. Why does that matter? Because a shorter relief section means less overhang and reduced vibration, especially when centering rigid materials like cast iron, tool steel, or pre‑hardened alloys. The stubby profile keeps the tip aligned, producing a more accurate center hole without wander.
Made from HSSE (cobalt‑enhanced high‑speed steel), it withstands the heat generated when spotting stainless steel or alloy steel. The double‑end design doubles tool life – when one end dulls, flip the tool. For left‑hand spindles on older lathes, custom machines, or specific setups where right‑hand tools are unusable, this left‑hand R‑type center drill is your solution.
Custom tip diameters and shank sizes available for OEM orders. Replace mismatched right‑hand tools and prevent spindle reversal damage with the correct left‑hand geometry.
📏 Standard sizes are shown in the charts above. For non‑standard diameters, lengths, or shank configurations, custom sizes are available – simply provide your requirements.
