Value Collection SM1500010 Chucking Reamer 5/32 in Cobalt

Product Description

The VALUE COLLECTION SM1500010 is a straight-shank chucking reamer designed to finish-ream drilled holes to a precise 5/32 inch (0.1562 inch decimal) diameter. Manufactured from cobalt steel, this reamer handles harder workpiece materials where high-speed steel tools would wear prematurely. The 6-flute spiral configuration with a right-hand cutting direction delivers a smooth bore finish with reduced chatter. At 4 inches overall length with a 1 inch flute length, the tool fits standard drill chucks and collet holders used on drill presses, lathes, and CNC machining centers. Machinists, tool-and-die makers, and maintenance technicians use chucking reamers like this one to hold tight hole-diameter tolerances after rough drilling.

This reamer is suited for precision hole finishing in metalworking applications across production, maintenance, and repair environments. The 0.1562 inch diameter targets the 5/32 inch nominal bore size common in small fastener clearance holes, dowel pin fits, and precision fixture work. The bright uncoated finish means the tool is ready to use as received and is compatible with most cutting fluids. It is sold individually and appropriate for both shop floor production runs and low-volume toolroom work.

Key Features

• Cobalt steel construction resists heat and wear when reaming harder alloys and stainless materials
• 6-flute spiral design provides smooth cutting action and improved finish quality
• Right-hand spiral and right-hand cutting direction for standard machine rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• Bright uncoated finish — no break-in required, compatible with water-soluble and oil-based cutting fluids
• 0.1562 inch decimal diameter for accurate 5/32 inch nominal hole sizing

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a drill chuck or collet capable of holding a straight-cylindrical shank at the 5/32 inch nominal diameter range.

Installation Notes

Chucking reamers should be installed in a rigid, well-centered holding device to minimize runout — excessive runout will cause oversize or out-of-round holes. Always pre-drill the hole undersize before reaming; a typical allowance is 0.005 to 0.015 inches of stock left for the reamer, but verify against your shop standards and workpiece material. Apply cutting fluid throughout the operation and never rotate the reamer in reverse, as back-spinning dulls the cutting edges rapidly. Secure the workpiece firmly before starting the spindle.
