SCLCR 20X20 09 turning tool – for longitudinal turning with light facing
20×20 mm indexable turning tool for a CCMT insert
Turning tool SCLCR 20X20 09 is an indexable turning tool designed for external turning on conventional and CNC lathes. The shank, with a cross section of 20×20 mm and a length of 125 mm, provides the rigidity required for industrial machining. 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 0903rr 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 turning tool is compatible with CCMT 09 inserts in various carbide grades — select the grade to match the workpiece material.

Typical applications of the SCLCR 20X20 09 turning tool
Cutting operations:
| ▸ | Longitudinal turning — the 95° angle provides stable cutting along the workpiece axis with light facing |
| ▸ | Medium machining and finishing of steel and cast iron — positive CCMT geometry provides low cutting forces and a smooth surface |
| ▸ | Machining shafts and bushings — a general-purpose tool for external turning of rotational parts |
| ▸ | Taper turning — machining tapered surfaces on CNC and conventional lathes |
| ▸ | CNC production runs — quick insert replacement and repeatable positioning |

Compatible CCMT 0903rr insert
CCMT 0903rr
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.
Installing and replacing the insert in the SCLCR 20X20 09 turning tool
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 1.5× the shank height without support |
| ▸ | 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 coolant during machining — it extends insert life and improves surface finish. When machining without coolant, reduce the cutting parameters by 20–30%.
Frequently asked questions — SCLCR 20X20 09
This tool accepts inserts CCMT 0903rr in any carbide grade. Select the grade to match the workpiece material: P (steels), M (stainless steel), K (cast iron), N (aluminum). You can find compatible inserts in the "Related products" section below.
The entering angle of 95° provides stable longitudinal turning with light facing. A typical angle for general-purpose machining on CNC and conventional lathes.
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.
