Value Collection SM33MT05 5MT Morse Taper Reamer Hss

Product Description

The VALUE COLLECTION SM33MT05 is a 5MT Morse Taper Reamer designed to finish-ream tapered bores to the No. 5 Morse Taper specification. Built from high-speed steel with a bright, uncoated finish, it delivers accurate taper sizing in machine tool spindles, drill press quills, and lathe tailstocks. The straight flute geometry provides consistent chip clearance and smooth cutting action. With a small end diameter of 1.4717 inches, a large end diameter of 1.8005 inches, and a 6.25-inch flute length, this reamer is suited for shops that need reliable OEM-spec taper restoration or fresh taper preparation in ferrous and non-ferrous workpieces.

This reamer is used in machine shops, toolrooms, and maintenance facilities where No. 5 Morse Taper bores must be sized or reconditioned. Typical applications include fitting drill chucks, arbors, and centers to spindles, as well as boring new taper sockets in custom fixturing. The 1.5-inch straight cylindrical shank seats securely in a standard machine collet or chuck. Right-hand cutting direction matches conventional spindle rotation on most milling machines, drill presses, and lathes.

Key Features

• 5MT Morse Taper profile for accurate No. 5 Morse Taper bore sizing
• High-speed steel construction for durability in both ferrous and non-ferrous materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight flute design provides smooth chip evacuation and consistent finish
• Right-hand cut matches standard spindle rotation
• 1.5-inch cylindrical shank for secure chuck or collet clamping

Compatibility

Designed for use in any machine tool spindle, tailstock, or fixture requiring a finished No. 5 Morse Taper bore. Fits standard collet chucks or drill chucks accepting a 1.5-inch straight cylindrical shank.

Installation Notes

A licensed machinist or experienced toolroom technician should perform Morse Taper reaming. Power down and lock out the machine before mounting or removing the reamer. Secure the straight shank firmly in a properly sized chuck or collet before operation, and apply appropriate cutting fluid throughout the reaming cycle to reduce heat and improve finish. Do not force the reamer through an undersized bore in a single pass; take progressive passes to the final taper dimension.
