Introducing the Carmex Tiny Tool Kit — KT5-20, a compact 20mm shank diameter bar holder system designed for quick, repeatable machining. Built for professionals, technicians, and hobbyists, this all-in-one kit puts six essential operations at your fingertips: boring, profiling, threading, chamfering, grooving, and face grooving. The kit includes a dedicated holder (K25) and a tidy, protective case that keeps every insert secure and ready for fast setup.

• All-in-one versatility: Covers boring, profiling, threading, chamfering, grooving, and face grooving in a single kit, so you can tackle multiple machining tasks without hunting for separate tools or changing setups.
• Secure, precise setup: The 20mm shank diameter bar holder delivers stable alignment for consistent cuts, and the included key helps you lock-in settings quickly for repeatable results.
• Compact, organized case: A durable, portable case with dedicated slots keeps every insert and accessory secure and easy to access, reducing downtime during tool changes.

With this kit, you streamline workflow, reduce downtime, and improve results across common metalworking operations. By having all essential inserts and the holder in one place, you can plan, set up, and complete tasks faster, from initial boring to final face grooving, while maintaining consistent quality and control over your process.
