Description
Carmex Carbide Tiny Tool – Face Grooving is a solid carbide bar engineered for precise face grooving. As part of the Tiny Tools family, it’s designed for professionals who need repeatable, straight grooves in metal parts.
Unlike rounded-groove options, this tool delivers straight grooves for clean walls and dependable seating surfaces. With a 6 mm minimum diameter and 2 mm groove width, it supports tight tolerances and compact setups.
- Straight-groove geometry: Produces consistently straight grooves with clean walls, ensuring predictable groove dimensions and reliable seating in each pass.
- Durable solid carbide (K20): High wear resistance for longer tool life in demanding face grooving tasks, reducing replacement frequency.
- Precisely sized for Tiny Tools: Designed with a 6 mm minimum diameter and 2 mm groove width to fit tight setups and deliver repeatable groove dimensions.
Designed to deliver consistent, straight grooves from the first cut, the Carmex Carbide Tiny Tool helps improve part fit and seal integrity in face-grooving tasks. The solid K20 carbide offers wear resistance for longer tool life, while the compact 6 mm minimum diameter and 2 mm groove width enable precise groove geometry in tight or small-diameter workpieces. This makes it a dependable choice for engineers, machinists, and hobbyists who demand predictable results and an efficient workflow in everyday groove jobs.
