Cutting Diameter (ØD): 24.0 mm nominal cutting diameter.
Renuka Tooling System
Operation Type: Spot facing and counterboring. It produces a flat 90° shoulder relative to the machine spindle axis.
Pilot Guide / Pre-Drill Requirement: This specific tool standard requires a minimum pre-drilled pilot hole of Ø8.0 mm to ensure radial stability and concentricity while the tool enters the cut.
Renuka Tooling System
Insert Capacity: Typically accommodates 2 indexable inserts positioned opposite each other to balance cutting forces and maximize feed rates.
2. Insert Identification (SCMT 09)
The tool body is machined with insert pockets precision-ground to fit standard SCMT 09T3... size inserts:
S (Shape): Square 90° indexable insert. Square inserts are used here because they offer robust cutting edge lines and 4 distinct cutting edges per insert.
C (Clearance Angle): 7° positive clearance. This minimizes friction on the face of the spot face cavity.
M (Tolerance): Precision class detailing factory-standard height and indexability parameters.
T (Fixing Style): Countersunk clamping hole designed for standard M3.5 Torx center screw fixing.
09 (Size Code): Nominally matching a 9.525 mm (3/8") Inscribed Circle (IC) with a metric cutting edge length of roughly 9.52 mm.
3. Matching Standard Hardware
To run this assembly safely on your CNC milling or boring machine, the standard pocket hardware kit required is:
Pocket Screw: M3.5 x T15 thread size.
Torx Wrench Key: T15
