Titan Usa TR94078 Chucking Reamer 0.063 in Hss 4 Flute

Product Description

The TITAN USA TR94078 is a straight-shank chucking reamer designed to finish-ream drilled or bored holes to precise tolerances in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate hole sizing in a range of ferrous and non-ferrous materials. The reamer measures 0.0630 inches in diameter with a 2.5-inch overall length (OAL) and a 0.5-inch flute length. Its 4-flute, right-hand cut configuration provides smooth material removal and consistent surface finish. This tool is part of the TITAN USA TR94 series and is suited for use in drill presses, CNC lathes, and manual lathes by machinists and toolroom technicians.

This chucking reamer is used in precision machining applications where hole diameter accuracy and surface finish are critical. Typical use cases include finishing through-holes and blind holes in production and job-shop environments. The straight cylindrical shank seats directly in a drill chuck or collet, making it compatible with standard machine setups. The small 0.0630-inch diameter makes it appropriate for fine-tolerance work in small-bore components such as hydraulic fittings, instrumentation parts, and similar precision assemblies.

Key Features

• 0.0630-inch (1.60 mm) reamer diameter for small-bore precision finishing
• High-speed steel (HSS) construction for durability across common machining materials
• 4-flute, right-hand cut design for smooth, consistent material removal
• Straight flute geometry suited for through-hole and shallow blind-hole reaming
• Bright, uncoated finish — no coating buildup to affect tolerance
• Straight cylindrical shank for direct chuck or collet mounting

Compatibility

Designed as an OEM-style replacement or direct substitute for straight-shank chucking reamers in the 0.0630-inch diameter range, compatible with standard drill chucks and collet holders used on drill presses, engine lathes, and CNC turning centers.

Installation Notes

Installation is performed by machinists or toolroom technicians. Secure the straight shank firmly in a drill chuck or collet before use, and verify runout before reaming to maintain hole tolerance. Always ream at the appropriate spindle speed and feed rate for the workpiece material — consult published HSS reamer speed-and-feed charts. Do not use this tool as a drill; pre-drill the hole to the correct undersize before reaming.
