Micro 100 QFR-069-12 Quick Change Full Radius Grooving Tool, Solid Carbide Tool, 0.069" (1.75 mm) Groove Width, 0.100" (2.54 mm) Projection, 0.370" (9.4 mm) Minimum Bore Diameter, 0.750" (19.1 mm) Maximum Bore Depth, 0.3750" (9.5 mm) Shank Diameter, 2" (51 mm) Overall Length: Industrial & Scientific. The MICRO 00 QFR-069-2 uncoated, solid carbide, full radius grooving tool for utilization in the Micro-Quik Change Tooling System . Designed and engineered for most machining applications that requires a full radius groove with a defined radii callout. Tools can be utilized for both roughing and finishing. Manufactured with close tolerances to ensure ultimate precision and performance. Tool's cutting edge/tip has a distinctive mirror like finish that significantly adds to material removal while improving surface finishes. The Micro-Quik Tooling System provides maximum centerline repeatability within plus or minus 0.0005" from tool to tool. When all of the components are used together, this unique system reduces machine setup, downtime, tooling costs, and tooling inventories all while boosting productivity. MICRO 00 Solid Carbide Tools feature more than just a micro-grain of excellent quality. Their substrate is in a class of its own resulting from exclusive treating processes that allow for vastly increased speed and feed rates. For over 45 years, MICRO 00 is a known industry leader and internationally acclaimed when it comes to solid carbide tooling. 。 。 。
