Value Collection SM0301230 Chucking Reamer 0.1230 in Hss

Product Description

The VALUE COLLECTION SM0301230 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.1230-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance on a range of workpiece materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With an overall length of 3.5 inches and a 7/8-inch flute length, this reamer is well suited to close-tolerance work in compact setups. Cutting action is right-hand, matching conventional machine rotation. Machinists, tool-and-die makers, and maintenance technicians install this type of reamer in drill presses, CNC mills, and lathes to bring drilled or bored holes to final size.

This reamer is rated as a dowel pin reamer, sized to match the 0.1230-inch dowel pin standard. It is intended for applications where a drilled hole must be brought to tight dimensional tolerance to accept a dowel pin or similar precision fastener. Typical use cases include fixture building, jig work, die sets, and assembly operations requiring repeatable, accurate hole sizing in ferrous and non-ferrous metals. It is not an over- or under-size reamer; it cuts to the nominal 0.1230-inch dimension.

Key Features

• 0.1230-inch reamer diameter matches 0.1230 D/P dowel pin specification
• High-speed steel (HSS) construction for durability across a range of metals
• Straight flute geometry suited to through-hole and short blind-hole reaming
• Bright, uncoated finish - ready to use as supplied
• Straight-cylindrical shank for compatibility with standard drill chucks and collets
• Right-hand cutting direction for use with conventional machine rotation

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, CNC machining centers, lathes, and similar machine tool setups that accept a straight-cylindrical shank tool requiring a 0.1230-inch finish diameter.

Installation Notes

A licensed machinist or qualified maintenance technician should install and operate this reamer in a properly secured machine tool. Power down and lock out the machine before mounting or removing the reamer from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Never exceed the recommended RPM range for the tool diameter and material being cut.
