A Drill Sleeve is an adapter used to reduce the size of a machine spindle taper to fit a smaller drill bit or tool with a different taper. It allows compatibility between drill bits and machines with varying Morse Taper (MT) sizes.

Types of Drill Sleeves

• Morse Taper (MT) Reduction Sleeves – Convert larger MT sizes to smaller ones (e.g., MT4 to MT3)
• Morse Taper (MT) Extension Sleeves – Extend the reach of a drill bit for deep hole drilling
• Tanged Drill Sleeves – Feature a tang for easy removal from the spindle
• Straight Shank Drill Sleeves – Used in drill presses and CNC machines

Size Range

• Available in MT1 to MT6 for various spindle and drill bit combinations

Features

• Made from hardened and precision-ground steel for durability
• Provides high concentricity and minimal runout for accurate drilling
• Corrosion-resistant coating for long-lasting performance
• Easy installation and removal for quick tool changes

Applications

• Used in drilling machines, lathes, and milling machines
• Enables the use of smaller drill bits in larger spindle tapers
• Common in metalworking, woodworking, and precision engineering

Drill Sleeves ensure flexibility and compatibility in machining operations, allowing for efficient and precise drilling across different machine setups.
