Holder M-4-A with Cutting Tip – 3- Angle 45°

The Holder M-4-A, equipped with a cutting tip, is designed to convert a Mira operated valve seat cutting machine for use with the Serdi tip system.
This "A-Type" holder supports 3-angle valve seat cutting at 45°, allowing for enhanced precision and compatibility during cylinder head reconditioning.
Ideal for professional engine builders upgrading from Mira to Serdi-style tooling, ensuring clean and accurate valve seat profiles.

The holder comes without the tip.
