Tungaloy 6815312 Insert Screw Indexable End Mills

Product Description

The TUNGALOY 6815312 is an insert screw designed to secure indexable cutting inserts in compatible toolholders. Insert screws are small but critical fasteners that clamp indexable inserts firmly against the pocket seat, maintaining precise positioning during cutting operations. This screw is specifically matched to square-shoulder end mill toolholders. Proper insert retention directly affects tool performance, surface finish, and operator safety, making the correct screw selection essential. Installation is typically performed by machinists, tool room technicians, or CNC setup personnel.

This insert screw is intended for use with indexable square-shoulder end mill toolholders that require insert-style clamping hardware. Square-shoulder end mills are commonly used in milling operations where 90-degree walls and flat floors are required. Keeping a supply of correctly matched insert screws on hand reduces downtime when screws are lost, stripped, or damaged during routine insert indexing.

Installation Notes

Insert screws should be installed by qualified machinists or toolroom technicians familiar with indexable tooling systems. Always power down and lock out the spindle before servicing toolholders or indexing inserts. Use the manufacturer-specified Torx or hex key for tightening to avoid stripping the screw head. Never reuse visibly damaged or deformed insert screws, as compromised fasteners can lead to insert ejection during operation.
