Value Collection SM01N0044 Chucking Reamer No. 44 Hss

Product Description

The VALUE COLLECTION SM01N0044 is a straight-flute chucking reamer ground to a No. 44 wire gauge diameter of 0.0860 inches. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate hole finishing in a wide range of metals and plastics. The reamer features four right-hand cutting flutes and a straight-cylindrical shank sized for secure chuck mounting on drill presses, lathes, and CNC machines. Overall length is 3 inches with a flute length of 0.75 inches, making it well suited for shallow, precision-tolerance holes in tight workpiece geometry.

This reamer is used in machine shop, tool room, and production environments where final hole sizing to wire-gauge tolerances is required. It is appropriate for light material removal after drilling, producing smooth, close-tolerance bores in ferrous and non-ferrous materials. Typical applications include fixture work, jig boring, and reaming pilot holes for dowel pins or close-fit fasteners. The compact flute length and small diameter make it a practical choice for instrument, aerospace, and precision-mechanical work.

Key Features

• No. 44 wire size diameter — 0.0860 inches for precise hole finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Four straight flutes with right-hand cutting direction
• Bright, uncoated finish — no coating interference on tight-tolerance holes
• Straight-cylindrical shank for direct chuck or collet mounting
• Compact 3-inch overall length suits short-reach and benchtop machine setups

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a suitable chuck or collet capable of holding a straight-cylindrical shank at this diameter range.

Installation Notes

Chucking reamers should be installed by a machinist or toolroom technician familiar with proper setup and feeds-and-speeds for reaming operations. Always secure the shank fully in the chuck or collet before operation and verify workpiece is clamped rigidly. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never use a reamer to remove more stock than required for finishing — pre-drill or bore to within a few thousandths of final size before reaming.
