TinyMiniTurn – Sleeve – SH725
IMPROVED TOOL LIFE
Long tool life - TinyMini-Turn and its chipping-resistant SH725 grade provided 30% increase in tool life. Excellent chip control - Featuring four peripheral coolant holes, Tungaloy’s new JBBS20-7-L100C-4N sleeve supplied streams of coolant jets directly to the cutting zone, dramatically reducing chip entanglement and re-cuts that was causing scratches on the finished surface. TinyMini-Turn tools with its new sleeve for improved coolant supply, are perfect combination for internal grooving of small bores.
