Titan Usa TR94168 Chucking Reamer 0.1185 in Hss 4 Flute

Product Description

The TITAN USA TR94168 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this 4-flute right-hand reamer delivers accurate, smooth bores in ferrous and non-ferrous materials. The reamer measures 0.1185 inches in diameter with a tolerance of +0.0002 to -0.0000 inches, making it suitable for close-tolerance work where final hole size matters. Overall length is 3.5 inches, with a flute length of 0.875 inches. The straight-cylindrical shank seats securely in standard drill chucks or collet holders used on lathes, drill presses, and CNC equipment.

This reamer is used in machine shop and production environments where a drilled hole requires finishing to a precise diameter. It fits residential and commercial shop workflows for light-to-medium material removal on pre-drilled holes. The TR94168 belongs to TITAN USA's TR94 series, which covers small-diameter chucking reamers in the 0.1000 to 0.1499 inch diameter range. Machinists and tool-and-die professionals typically select this reamer for reaming dowel pin holes, bearing bores, and precision-fit assemblies where diameter control is critical.

Key Features

• 0.1185 inch diameter with tight tolerance of +0.0002 to -0.0000 inches for precise hole sizing
• High-speed steel (HSS) construction provides durability in a wide range of workpiece materials
• 4-flute straight configuration delivers consistent chip evacuation and smooth finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard chucks and collets without special toolholders
• Bright, uncoated finish suits general-purpose reaming where coatings are not required

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with standard straight-shank collets or drill chucks accepting small-diameter tooling.

Installation Notes

Installation and use should be performed by qualified machinists familiar with metal-cutting operations. Always secure the workpiece firmly and ensure the machine spindle is fully stopped before changing tooling. Pre-drill the hole to the correct pilot diameter before reaming to avoid excessive material removal and tool deflection. Do not use a reamer to enlarge a hole by more than the recommended stock allowance for the diameter range, as this can cause chatter and reduce finished bore quality.
