Starrett DCH0438 Deep Cut Bi-Metal Holesaw 111mm | DCH0438-G

Starrett DCH0438-G Deep Cut Bi-Metal Holesaw, 111mm

Starrett DCH0438-G is a deep cut bi-metal holesaw designed for clean, controlled cutting of larger diameter holes, with an increased cutting depth that helps when working through thicker materials and tubular sections.

With a 111mm diameter, the DCH0438 holesaw is a practical choice for trade drilling tasks where stable cutting action and long-lasting tooth performance matter across a range of site and workshop applications.

Key Features

• Deep Cut design (51mm cutting depth): Helps you cut through thicker sections and is particularly useful when drilling tubes where there may be a need to cut both sides.
• Bi-metal construction with HSS teeth: Built for strong cutting performance with enhanced heat and wear resistance for improved working life.
• Variable pitch tooth form (4–6 TPI): Supports an aggressive cutting action with reduced vibration for smoother control.
• Improved kerf clearance: Promotes efficient swarf removal to keep the cut progressing cleanly.
• Thread size 5/8"–18: Designed to fit Starrett arbors using the specified thread.
