Built from steel, it accepts CN..32. series inserts held in place by a clamp and screw method, providing repeatable insert positioning and secure clamping under negative rake cutting conditions. The shank measures 0.625 inches wide by 0.625 inches tall, with an overall length of 4 inches and a head length of 1 inch. The back-of-bar to cutting edge distance is 0.875 inches. This toolholder is installed by machinists and toolroom technicians working in production and job-shop turning environments.\u003c\/p\u003e\u003cp\u003eThe HERTEL 1000101 is suited for external turning applications where negative rake geometry is preferred for interrupted cuts, harder workpiece materials, or heavier feeds. The 5-degree lead angle positions the insert for efficient chip flow and edge engagement. It is a standard-shank toolholder compatible with tool blocks and turrets sized for 5\/8-inch square shanks. This part fits the Multi-Option series and is a direct catalog replacement for applications calling for MCLNR or L103A style holders. Coolant-through capability is not included in this holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand MCLN toolholder style with 5-degree lead angle\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry suited for heavy stock removal and hard materials\u003c\/li\u003e\n\u003cli\u003eClamp and screw insert holding method for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eAccepts CN..32. series inserts with 3\/8-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity in production turning environments\u003c\/li\u003e\n\u003cli\u003e5\/8-inch square shank fits standard lathe tool blocks and turrets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eTakes CN..32. indexable inserts (complete insert compatibility: CN.. 322).
