S08 SCLCR 06 boring bar – for internal turning and bore finishing
Internal turning tool for machining bores from Ø11 mm
Boring bar S08 SCLCR 06 is an indexable boring bar designed for longitudinal turning and bore finishing with diameters from 11 mm. The round steel shank with a diameter of Ø8 mm and a length of 100 mm provides cutting stability even with greater tool overhang. The geometry with an entering angle of 95° allows turning along the wall with simultaneous light facing.
In the central screw clamping system (S), the screw secures the CCMT 0602rr insert through its hole, so only one screw needs to be loosened for replacement. The positive geometry of the 80° diamond insert with 2 cutting edges is well suited to finishing, providing low cutting forces and a smooth machined surface. The boring bar is compatible with CCMT 06 inserts in various carbide grades — select the grade to match the workpiece material.

Typical applications of the S08 SCLCR 06 boring bar
Cutting operations:
| ▸ | Longitudinal boring — enlarging and finishing cylindrical bores from Ø11 mm |
| ▸ | Bore finishing — positive CCMT geometry provides low cutting forces and a smooth surface |
| ▸ | Internal taper turning — bearing seats, internal chamfers, Morse tapers |
| ▸ | Light facing — the 95° angle allows machining the face inside the bore |
| ▸ | CNC production runs — repeatable cutting edge positioning and quick insert replacement in the holder |

Compatible CCMT 0602rr insert
CCMT 0602rr
The cutting insert is not included in the set — must be purchased separately. CCMT insert. Positive geometry means that the insert is single-sided and has 2 cutting edges, providing low cutting forces and good surface quality.
Select the insert grade to match the workpiece material: P (structural steels), M (stainless steel), K (cast iron), N (aluminum). You can find compatible inserts in the section "Related products" below.
Insert installation and replacement for the S08 SCLCR 06 boring bar
Instructions for the center screw clamping system (S)
Insert replacement procedure step by step
1 Unscrew the screw
Unscrew the center screw 2-3 turns
2 Clean the insert seat
Remove chips and debris
3 Install the insert
Position in the seat
4 Tighten the screw
Torque 0.6–1.2 Nm
Important: Do not exceed the recommended tightening torque — this may damage the thread in the seat or crack the insert.
Checks before starting work:
| ▸ | Tool overhang — do not exceed 4×d (32 mm) without support; use vibration damping for greater overhang |
| ▸ | Cutting edge height — set the cutting edge at spindle centerline height |
| ▸ | Insert seat condition — check that the contact surface is not damaged or worn |
| ▸ | Secure clamping — the insert must have no play in the seat |
| ▸ | Indexing — when an edge wears out, rotate the insert to a fresh edge (2 edges in total) |
Note: Use internal coolant (through the spindle) for boring whenever possible. When machining without coolant, reduce cutting parameters by 20–30%. Long tool overhang promotes vibration — if vibration occurs, reduce the depth of cut and increase the feed.
Frequently asked questions — S08 SCLCR 06
The minimum bore diameter is Ø11 mm. In smaller bores, the tool head interferes with the machined wall, preventing proper cutting.
For a steel shank of Ø8 mm, the recommended maximum overhang without damping is 4×d, or 32 mm. Above this value, vibration may occur — reduce the depth of cut or use a vibration-damped boring bar.
The CCMT insert has positive geometry (clearance angle 7°), which means it is single-sided with 2 cutting edges. When one edge wears out, rotate the insert to a fresh edge.
