Value Collection SM33MT04 4MT Morse Taper Reamer Hss

Product Description

The VALUE COLLECTION SM33MT04 is a 4MT Morse taper reamer designed to finish-ream tapered bores to precise dimensional tolerances. It features a straight flute geometry with a right-hand cut, machined from bright uncoated high-speed steel. The small end diameter measures 1.0167 inches and the large end diameter measures 1.2893 inches, spanning the standard 4 Morse taper profile. The straight shank measures 1.25 inches in diameter, the flute length is 5.25 inches, and the overall length is 8.5 inches. Machinists and toolroom technicians use this reamer to bring tapered bores to final size for tool holders, arbors, spindles, and similar taper-fit applications.

This reamer is suited for use in manual lathes, knee mills, drill presses, and toolroom machines where a 4MT bore must be finish-reamed to accept a Morse taper shank. It is appropriate for ferrous and non-ferrous metals in both production and maintenance environments. The high-speed steel construction allows use at conventional cutting speeds without coolant in light-duty operations, though flood coolant is recommended for extended runs or tougher alloys. Typical users include machinist trades, tool-and-die shops, and maintenance departments reconditioning taper bores.

Key Features

• 4MT Morse taper profile with 1.0167-inch small end and 1.2893-inch large end diameter
• High-speed steel construction provides good wear resistance at standard cutting speeds
• Straight flute geometry suits a wide range of materials and offers easy chip clearance
• Right-hand cut for use with standard spindle rotation
• Bright uncoated finish allows visual inspection of cutting edge condition
• 1.25-inch straight (cylindrical) shank for secure chuck or collet holding

Compatibility

Designed as an OEM-style replacement or new-installation reamer for any application requiring a finished 4 Morse taper bore.

Installation Notes

This tool is installed and operated by qualified machinists following established shop practices. Secure the straight shank firmly in a suitable chuck or collet before use, and verify the workpiece is rigidly fixtured. Apply appropriate cutting fluid to extend tool life and improve surface finish. Never exceed the recommended feed rate for the workpiece material, and inspect cutting edges before each use to avoid dimensional error.
