MT3 Shank Precision Boring Head Set

The Sealey MT3 Shank Precision Boring Head Set is a specialist milling accessory designed for achieving accurate, fine-tolerance bored holes on milling machines and machining centres. Precision boring is a critical operation in engineering and metalworking environments where standard drill bits cannot achieve the required dimensional accuracy. This set combines an MT3 (Morse Taper 3) shank with a precision boring head, allowing machinists and toolroom engineers to produce smooth, accurately sized bores to tight specifications. The MT3 taper shank provides a secure, self-holding connection to compatible milling machine spindles, ensuring concentricity and minimising vibration during cutting. This makes the set well suited to workshop machining tasks where repeatability and surface finish quality are essential.

Features and Benefits:

• MT3 Morse Taper shank for secure, self-holding spindle connection
• Precision boring head for fine-tolerance hole sizing
• Suitable for use on milling machines and machining centres
• Ideal for toolroom, engineering workshop, and production machining applications
