Value Collection ST09MTM1 1MT Morse Taper Reamer Hss

Product Description

The VALUE COLLECTION ST09MTM1 is a 1MT Morse taper reamer designed to finish and size tapered holes to precise Morse Taper No. 1 specifications. Manufactured from high-speed steel with a bright uncoated finish, this straight-flute reamer cuts on the right-hand rotation and delivers clean, accurate taper bores in ferrous and non-ferrous materials. The small end diameter measures 0.3674 inches and the large end diameter measures 0.517 inches, with a 3-inch flute length and an overall length of 6-5/16 inches. The tapered shank measures 2.8125 inches in diameter. It is a standard tool for machinists, tool-and-die makers, and maintenance technicians working on spindles, arbors, and machine tool sockets.

This reamer is suited for job shop, production, and maintenance applications where Morse Taper No. 1 holes must be precisely finished or restored. Typical use cases include fitting Morse taper tooling into drill press spindles, lathes, milling machines, and similar machine tool sockets. The straight-flute geometry makes it particularly effective in through-bore applications and materials that machine cleanly without requiring a spiral flute to break chips.

Key Features

• Taper designation: 1MT (Morse Taper No. 1) for standard machine tool fitment
• Small end diameter: 0.3674 inches; large end diameter: 0.517 inches
• Straight flute geometry suited for through-bore and clean-machining materials
• Right-hand cut for use with standard spindle rotation
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Bright uncoated finish for general-purpose machining applications

Compatibility

Designed as a standard OEM-style replacement and production reamer for any application requiring a finished Morse Taper No. 1 bore.

Installation Notes

This reamer is installed and operated by machinists using a lathe, milling machine, or drill press running at appropriate low speeds with cutting fluid applied. Always secure the workpiece and ensure the spindle and tooling are properly aligned before engaging the reamer. Avoid running dry, as lubrication extends tool life and improves surface finish. Inspect the cutting edges before each use and remove from service if chipping or wear is evident.
