Sandvik Coromant 6259473 Corner Chamfer End Mill 1.5mm

Product Description

The SANDVIK COROMANT 6259473 is a solid carbide corner chamfer end mill designed for precision chamfering and edge-breaking operations on ferrous and exotic workpiece materials. Built to a 1.5 mm cutting diameter with a 45-degree chamfer angle, it features a TiAlN PVD coating that extends tool life under dry and semi-dry cutting conditions. The 4-flute, single-end geometry provides a balance of chip evacuation and surface finish capability. With a 10 mm straight-cylindrical shank held to h6 tolerance, this tool seats securely in collet and shrink-fit holders. Overall length is 100 mm, and the length of cut measures 4.25 mm. Licensed machinists and CNC tool setters in job shops and production environments are the primary users.

This end mill is suited for chamfering and finishing operations on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The low helix and straight flute geometry make it appropriate for rigid setups where controlled chip flow and consistent chamfer width are required. It is a single-end tool intended for use in vertical and horizontal machining centers as well as CNC milling machines. The normal pitch and non-variable index design simplify programming for repeat chamfer passes.

Key Features

• 45-degree chamfer angle with 4.25 mm length of cut for consistent edge-break geometry
• TiAlN PVD coating improves heat resistance and wear life on hard and abrasive materials
• 4 right-hand flutes with straight flute type support both roughing and finishing passes
• 10 mm straight-cylindrical shank with h6 tolerance for precise collet and shrink-fit seating
• Chipbreaker geometry reduces cutting forces and aids chip control on difficult materials
• Rated for steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO P, M, K, S, H)

Compatibility

Designed as an OEM Sandvik Coromant replacement end mill in the 1C050 series. Compatible with standard collet chucks, shrink-fit holders, and hydraulic holders accepting a 10 mm shank diameter. Refer to the manufacturers catalog number 1C050-0150-045-XA when cross-referencing tool catalogs.

Installation Notes

Installation should be performed by a qualified machinist or CNC tool setter following the machine tool manufacturer's spindle and holder specifications. Power down and lock out the machine before changing tooling. Confirm holder runout before engaging the cut, as excessive runout will accelerate edge wear on small-diameter tools. Do not exceed the tool's rated depth of cut for the workpiece material being machined.
