Alvord Polk 10237 Chucking Reamer 0.145 in Hss Straight Shank

Product Description

The ALVORD POLK 10237 is a straight-shank chucking reamer designed to finish-ream drilled holes to a precise diameter of 0.145 inches. Constructed from high speed steel with a bright polished finish, it delivers clean, accurate cuts in ferrous and non-ferrous materials. The right-hand cutting direction and 4-flute straight configuration provide smooth chip evacuation and consistent hole geometry. With a tolerance of +0.0002 to -0.0000 inches, this reamer holds tight dimensional control for precision fit applications. Machinists and tool-and-die technicians use it in drill presses, lathes, and CNC machining centers where repeatable hole sizing is required.

This reamer is suited for production and maintenance machining environments where accurate hole finishing is critical. The 1-inch flute length accommodates shallow-to-moderate depth reaming tasks, while the 4-inch overall length provides adequate reach and rigidity in standard machine setups. It is appropriate for use on steel, cast iron, aluminum, brass, and similar machinable materials. The straight shank seats directly into a drill chuck or collet without the need for a taper adapter, simplifying tool changes on the floor.

Key Features

• 0.145-inch reamer diameter with a close tolerance of +0.0002 to -0.0000 inches for precision hole sizing
• High speed steel construction provides hardness and wear resistance across a broad range of workpiece materials
• Bright polished finish reduces friction and promotes smooth cutting action
• 4-flute straight configuration supports chip clearance and consistent surface finish
• Right-hand cutting direction compatible with standard machine rotation
• Straight shank fits directly into drill chucks and collets without adapters

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, lathes, and machining centers that accept straight-shank tooling in the applicable diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Secure the straight shank firmly in a drill chuck or collet before operation and verify runout before cutting. Always reduce spindle speed and apply cutting fluid when reaming to extend tool life and achieve the specified tolerance. Inspect the reamer for chips or wear before each use to avoid dimensional deviation in finished holes.
