The Right Tools for Tough Jobs

Whether the job calls for a precision finish or a difficult taper, you need a cutting tool that delivers every time. When the tolerances are tight and the finish must be perfect, you need a reamer that won't chatter, rifle, or vibrate. GAMMONS®' standards and custom reamers are produced from the highest quality steel, under demanding standards, to offer you unparalleled performance on every job.

Custom Performance with Custom Reamers

Some jobs simply can't be accomplished with off-the-shelf tools. GAMMONS® offers personalized service in the design and production of a reamer that will meet the precision need of any job. As originators of some speciality reamers, we offer years of knowledge and experience manufacturing tools that cannot be produced anywhere else.

High Helix Delivers Superior Quality

GAMMONS® manufactures even our standard reamers in the high helix design to provide the greatest accuracy and highest precision. Fast spiral fluted reamers deliver shear cutting action and increased surface contact without chatter, deflection, or vibration. The high helix design also allows for superior chip removal, avoiding costly scoring and binding.

"We tried other reamers, but we got buried in scrap. The cheap reamers ended up costing us much more than the Gammons' reamers. We went right back to Gammons."

"We have to hold tolerances and angles that other companies won't touch. Gammons custom work is superb. Their reamers can't be matched. They last longer. Hold the edge better. They let us give our customers products with a precision finish. Products we're proud of."

"Our products are clear acrylic, and finish is everything. We just won't consider anything but a Gammons Hoaglund reamer."
