Description
Product Overview
Whether you are breaking sharp edges on a freshly milled profile, deburring cross-holes, or spotting for a drill, an indexable chamfer mill is one of the most frequently used tools in any CNC carousel. This Japanese-Made 16mm 45-Degree Chamfer Tool (SC1645CSP) is a highly rigid, indexable cutting solution designed to make quick work of your edge-breaking and hole-chamfering operations.
- 45-Degree Profile: Cut at a true 45 degrees, this tool is absolutely perfect for milling clean, consistent chamfers on holes or running profiling passes along the outer boundaries of your machined parts.
- 16mm Straight Shank: Features a robust 16mm straight shank, making it easy to grip rigidly in an ER collet, milling chuck, or standard end mill holder.
- Indexable Efficiency: Unlike solid carbide chamfer mills that require expensive regrinding when they get dull, this tool uses indexable carbide inserts. When an edge wears out, you simply rotate the insert to a fresh cutting edge and get right back to machining, saving both time and tooling budget.
- Bonus Japanese Carbide: Finding the right inserts for a used tool can sometimes be a headache, so we have completely removed that problem. This tool comes loaded with an installed insert (with only one edge used), PLUS 4 brand-new Japanese carbide inserts to keep your spindles turning for a long time.
Condition
Used (Great Condition / Includes 4x New Inserts).
This indexable chamfer mill is in great used condition and is completely ready to run.
- Tool Body: The tool steel body and shank show typical, minor cosmetic handling marks from normal shop use, but the insert pocket is clean, undamaged, and provides excellent seating for the carbide. The locking screw threads smoothly.
- The Inserts: The currently installed insert has been used on just one face, leaving the other edges completely fresh. More importantly, it includes 4 brand-new inserts safely in their packet, providing massive immediate value.
Brand Information
Made in Japan (OEM / Unbranded) While the shank is proudly stamped with “Made in Japan” and the part number “SC1645CSP”, the specific manufacturer’s logo is not present. It is incredibly common in the Japanese machine tool industry for high-end OEMs to produce top-tier tooling for machine builders or large distributors without stamping a proprietary brand name. You are getting genuine Japanese tool steel and carbide quality without paying the brand-name premium.
