Toolex Hand Reamer - Spiral Flute - Straight Shank - HSS - H5 - 12.45mm

The Toolex Hand Reamer is a precision manual tool designed to bring drilled holes to an exact 12.45 mm size. Built around an intermediate HSS (M2) core with a left-hand spiral flute and right-hand cutting, it delivers clean, accurate reaming in a variety of materials. It’s a versatile choice for engineers, fabricators, tradespeople, and hobbyists who value reliable hole quality and finish.

Made to order by Toolex Ltd, this reamer uses DIN 206-B geometry with ISO H5 tolerance to ensure consistent results. Please allow 24–48 hours for despatch. If a listing shows “in stock,” that refers to blanks ready to be manufactured into your reamer, not a finished unit on the shelf.

• ISO H5 tolerance with DIN 206-B geometry: Delivers tight hole size control and a consistent finish for repeatable parts.
• Left-hand spiral flute with right-hand cutting: Optimizes chip evacuation and cutting action for cleaner holes and reduced chatter in manual reaming tasks.
• Straight shank in HSS (M2) for durability: Provides rigid guidance, long tool life, and easy compatibility with standard hand reaming setups.

Using this reamer helps you achieve controlled hole diameters quickly and consistently, reducing the need for post-reaming corrections. The robust M2 HSS core resists wear, while the straight shank ensures stable guidance in manual setups, improving productivity and overall part quality—hole to hole, job after job.
