Sutton 4mm Hand Reamer DIN206 - High Speed Steel HSS

Sutton Tools is an Australian-owned manufacturer of precision cutting tools and threading accessories, supplying tradespeople, engineers, and manufacturing operations across Australia and internationally. Their product range spans taps, dies, drills, endmills, holesaws, and related tooling — all engineered to perform consistently under real industrial conditions. AIMS Industrial supplies the Sutton Tools range to Australian businesses as part of our commitment to stocking quality, trusted brands.

Sutton adjustable reamers and precision boring tools are used to bring drilled or bored holes to a precise finished diameter with the close tolerance and surface finish required for bearing fits, pin fits, and precision mechanical assemblies.

Where this product is used

Used in engineering workshops and toolrooms for finish sizing holes to close tolerances that drilling alone cannot achieve.

• Finishing drilled or bored holes to H7 or tighter fits in bearing housings, pin holes, and precision assembly locations in engineering components.
• Adjustable reamer use across a range of hole diameters using a single tool, with adjustable blades set to the exact finished size required.
• Precision sizing of hydraulic cylinder bores, valve bores, and other pressure-system holes where bore diameter directly affects leakage and performance.

Key specifications

Selecting the right option

Always drill and rough-bore the hole undersize before reaming — a reamer removes only a small finishing allowance (typically 0.1–0.25 mm). Use cutting fluid throughout, run at approximately half the drill speed for the same diameter, and use a steady, non-reversing feed. Adjustable reamers can be set to specific sizes within their range — confirm the blade setting with a micrometer before use.
