Hertel 72291107 Chucking Reamer 5/32 in Hss Straight Shank

Product Description

The HERTEL 72291107 is a straight-shank chucking reamer designed to bring bored or drilled holes to precise finished diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, it is well-suited for general-purpose reaming in a wide range of ferrous and non-ferrous materials. The reamer measures 0.1562 inches in decimal diameter (5/32 inch nominal) with a 3-1/8 inch overall length and a 1 inch flute length. Four straight flutes cut in a right-hand direction, providing smooth material removal and accurate sizing in both manual and machine setups. Machinists and tool-and-die professionals rely on this style of reamer for production and repair work where hole tolerance is critical.

This chucking reamer is suited for use in drill presses, CNC machining centers, lathes, and hand-held drilling equipment equipped with a suitable chuck. The straight-cylindrical shank allows secure clamping in standard drill chucks and collet systems without specialized tooling. Typical applications include finishing pilot holes, reaming bearing bores, and sizing holes for close-tolerance dowel or pin fits in metalworking, maintenance, and repair environments.

Key Features

• 5/32 inch (0.1562 inch) nominal reamer diameter for precise hole finishing
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• 4 straight flutes with right-hand cutting direction for smooth, controlled material removal
• Bright uncoated finish — ready for use and compatible with most cutting fluids
• Straight-cylindrical shank for direct chucking in standard drill chucks and collets
• Compact 3-1/8 inch overall length suits tight-clearance and bench-top applications

Compatibility

Designed as a standard chucking reamer for use in machine tools and hand-held drilling equipment that accept a straight-cylindrical shank. Verify chuck capacity and bore diameter requirements before installation.

Installation Notes

Chucking reamers are installed by machinists and toolroom technicians using standard drill chucks or collet systems. Always power down and lock out the machine before securing or removing the reamer from the chuck. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Never use a reamer to remove excessive material — pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
