Available

AIMS Industrial supplies the Sutton Tools range to Australian businesses as part of our commitment to stocking quality, trusted brands.
Sutton R100 hand reamers are fixed, single-diameter finishing reamers — each size is ground to that exact diameter, not an adjustable range. They are turned by hand with a tap wrench to bring a drilled or bored hole to its final precise diameter and surface finish, where a machine reamer or drill press isn’t being used.
Where this product is used
Used in engineering workshops, toolrooms, and on-site maintenance work for hand-finishing holes to a precise diameter and H7 tolerance, without needing a machine reamer or drill press.
- Hand-finishing drilled or bored holes to H7 tolerance in bearing housings, pin holes, and precision assembly locations.
- Bench and toolroom work calling for an exact, fixed hole diameter.
- Field and maintenance work where a drill press or machine reamer isn’t available or practical.

Selecting the right option
Select the reamer matching the exact finished hole diameter required — this is a fixed-size reamer, so choose the size precisely rather than assuming an adjustment range. Drill or bore the hole undersize first (typically 0.1–0.25mm undersize, depending on diameter), then hand-ream using cutting fluid and a steady, non-reversing turn with a tap wrench.
