KORRETTO · Lathe center series
Half-Notched Center
Half-notched centers are designed for fixed support applications where tool clearance or workpiece access is limited. The notched structure provides support while leaving space for cutter approach or special machining conditions.
Send the Morse taper, workpiece size, tool clearance requirement, support direction and machining process, and we will help check whether this half-notched center series fits your setup.
Product Overview
The KORRETTO half-notched center is used for fixed center support where a standard full-profile dead center may interfere with tool access. It is suitable for special turning or grinding conditions that require both support and clearance.
Typical Applications
- Fixed tailstock support with tool clearance
- Special turning operations
- Grinding and finishing setups
- Workpieces requiring access near the support point
- Applications where a standard dead center profile may interfere

Selection Notes
Before selecting a half-notched center, confirm the Morse taper, workpiece size, tool clearance requirement, support direction and machining process. This series is suitable when fixed support is needed but the tool or workpiece requires additional clearance.
FAQ
What is a half-notched center used for?
A half-notched center is used when the workpiece needs center support while still leaving tool access near the end face or shoulder area. It is selected for special turning conditions that need clearance around the supported end.
Is it a standard live center or a special center?
It is a special center for relief and clearance applications. Final use should be confirmed according to the support condition, machining path and machine setup.
What machine taper should be confirmed?
Please confirm the tailstock taper or machine center interface before selection. The half-notched center must match the machine taper correctly.
What workpiece support condition should be checked?
Please confirm the center-hole form, end-face machining requirement, clearance direction and support position. These factors determine whether a half-notched center is appropriate.
What speed or load should be considered?
Please confirm the operating speed, support load and machining condition near the supported end. The notch structure must still match the workpiece support requirement safely.
How is it different from a standard center?
A standard center provides full-point support. A half-notched center leaves machining clearance near the supported end and is selected when a standard full-point shape would interfere with the tool path.
What should be checked before installation?
Check the machine taper, notch orientation, workpiece support position and tool clearance path before installation. The center and mating surfaces should be clean and properly aligned.
What information is needed for quotation?
Please provide the machine taper, workpiece drawing, center-hole size, clearance requirement, speed range and machining process.
