SRACL 20x20 K08 turning tool – for facing and longitudinal turning
Professional 20×20 mm indexable turning tool for an RCMT insert
Turning tool SRACL 20x20 K08 is a professional 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 90° allows facing and turning along a shoulder.
The central screw clamping system (S) ensures the highest cutting edge positioning repeatability and easy replacement of the RCMT 0804rr insert. The positive geometry of the round insert with a continuous cutting edge is well suited to finishing, ensuring low cutting forces and a smooth machined surface. The tool is compatible with RCMT 08 inserts in various carbide grades — select the grade to match the workpiece material.
Typical applications of the SRACL 20x20 K08 turning tool
Cutting operations:
| ▸ | Facing — the 90° angle provides uniform cutting of the end face |
| ▸ | Turning along shoulders — the right angle allows machining 90° corners |
| ▸ | Machining steel and cast iron materials — positive RCMT geometry provides low cutting forces |
| ▸ | Turning steps and flanges — precision machining of diameter transitions |
| ▸ | CNC production runs — repeatable cutting edge positioning and quick replacement |

Compatible RCMT 0804rr insert
RCMT 0804rr
The cutting insert is not included in the set — must be purchased separately. RCMT insert. Positive geometry means that the insert is single-sided and has a continuous cutting edge, 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 SRACL 20x20 K08 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 0.8–1.5 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 center height (±0.05 mm) |
| ▸ | Insert seat condition — check that the contact surface is not damaged or worn |
| ▸ | Secure clamping — the insert must have no play in the seat |
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 — SRACL 20x20 K08
This tool accepts inserts RCMT 0804rr 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 90° provides facing perpendicular to the axis and turning along shoulders. Ideal for machining flanges, steps, and right angles on the workpiece.
Select the grade according to the ISO material group: P (non-alloy and alloy steels), M (stainless and heat-resistant steel), K (gray and ductile cast iron), N (aluminum and non-ferrous metals). Grades labeled "universal" are suitable for most applications.
