Product Specifications:
Left‑hand cutting tools are a necessity when your machine spindle runs counter‑clockwise, or when you need to prevent screw‑out in certain setups. This HSSE double‑end R‑type center drill is ground for left‑hand rotation, making it a perfect match for those spindles.
The 4mm tip creates a reliable center hole for medium‑size workpieces, while the 60° cone conforms to DIN333 for universal compatibility. The protective R10 radius shoulders prevent the drill from over‑traveling, protecting the finished face of your part – especially valuable when adding a center hole after turning.
With a total cutting length of 15.11mm per end (10.6mm cone plus 4.51mm straight relief), each end provides ample sharpened area before needing re‑sharpening. The double‑end design effectively doubles tool life. HSSE material handles stainless steel, carbon steel, aluminum, and copper‑zinc alloys with good wear resistance. The 10mm straight shank fits standard ER collets.
For workshops with left‑hand spindles, or for those who prefer left‑hand tools for specific operations, this center drill offers the same precision and durability as its right‑hand counterpart. Custom tip diameters and shank sizes are available. Keep one in your tool crib for reverse‑rotation jobs.
📏 Standard sizes are shown in the charts above. For non‑standard diameters, lengths, or shank configurations, custom sizes are available – simply provide your requirements.
