Description
Toolex HSS-E Countersinks deliver precise, clean countersinks with a robust 3-flute design and a 90° angle, built for reliable performance in metalworking and DIY projects. The M12 shank and 25mm length suit standard tool holders, enabling secure mounting and straightforward swapping in drills, milling machines, or handheld drivers.
- 3-Flute Configuration: Optimizes chip evacuation and reduces clogging, delivering consistent chamfers on tougher materials.
- 90° Countersink Angle: Provides a precise, standard 90-degree chamfer for flush seating of flat-head screws.
- HSS-E with Cobalt Core: High-speed steel with cobalt enhances hardness and heat resistance for durable performance under demanding cuts.
- TiN Coating: Titanium nitride coating lowers friction, reduces wear, and extends tool life by maintaining edge sharpness longer.
- M12 Shank: Secure mounting in compatible tool holders and collets for stable, vibration-free cutting.
- 25mm Length: Compact length offers excellent control in tight spaces without sacrificing cutting rigidity.
- Wide Application Range: Suitable for countersinking holes in metals and plastics, helping you achieve clean, professional screw seating.
Using these countersinks delivers cleaner, more accurate chamfers with less effort. The combination of a 3-flute design, cobalt-alloy core, and TiN coating reduces heat buildup and wear, so you can work longer between tool changes. The 90° angle ensures a consistent seating for screws, while the robust M12 shank and compact 25mm length make it easy to integrate into existing workflows and tight workspaces.
