Carmex SR0620K14C Indexable Thread Mill 0.62 in Solid Carbide

Product Description

The CARMEX SR0620K14C is an indexable thread mill designed for precision internal and external thread milling operations on CNC machining centers. Built from solid carbide, this toolholder accepts one IE-style insert secured by a screw-lock holding method, delivering consistent thread form accuracy across a range of materials. The cutting diameter measures 0.62 inches with a 1/2 inch shank diameter and a neck diameter of 0.50 inches. Through-coolant capability is integrated into the body, allowing direct coolant delivery to the cutting zone for improved chip evacuation and tool life. The overall length is 7.0 inches. This tool is intended for use by machinists and CNC programmers working in production or job-shop environments.

The SR0620K14C is suited for thread milling applications in both ferrous and non-ferrous materials where a single-point or full-form thread mill approach is required. The SR-style toolholder body accepts a 14 mm IE insert, referenced by key designation K14 with insert screw S14. Through-coolant support makes it particularly effective in deep-thread or blind-hole applications where chip control is critical. This tool is appropriate for use on vertical and horizontal machining centers with through-spindle coolant capability.

Key Features

• Solid carbide toolholder body for rigidity and vibration resistance during thread milling
• Accepts one IE-style indexable insert, 14 mm size, for cost-effective edge replacement
• Through-coolant design directs coolant to the cutting zone for chip evacuation and thermal control
• 0.62 inch cutting diameter with 0.50 inch neck and 1/2 inch shank for reach into tight bores
• Screw-lock insert holding method for secure, repeatable insert indexing
• 7.0 inch overall length supports thread milling in deeper workpiece features

Compatibility

Designed for use with IE-style indexable threading inserts, 14 mm size, using insert screw S14. Compatible insert styles are designated I and E per the supplier specification. Intended for SR-style toolholder configurations on CNC milling platforms with through-spindle coolant.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Secure the shank in an appropriate ER or hydraulic collet chuck rated for 1/2 inch diameter tooling, verifying runout before cutting. Insert indexing requires the correct T-handle torx or hex key matching the S14 insert screw specification. Confirm through-coolant passages are clear and that machine spindle coolant pressure is compatible with the toolholder design before operation.
