Hertel 72010309 Chucking Reamer 0.1030 in 4 Flute Hss

Product Description

The HERTEL 72010309 is a high-speed steel (HSS) chucking reamer designed to bring finish-bored or drilled holes to precise final diameter. Sized at 0.1030 inches in diameter with a 3.5-inch overall length and a 0.875-inch flute length, this reamer fits the 0.1000 to 0.1499 inch decimal inch range. The straight-cylindrical shank seats directly in drill chucks and collet holders. Four straight flutes with a right-hand cutting direction make it suitable for general-purpose reaming on lathes, drill presses, and CNC machining centers. The bright, uncoated finish makes tool wear easy to inspect. Machinists, tool-and-die makers, and maintenance technicians use this style of reamer for close-tolerance hole finishing in metal workpieces.

This chucking reamer is appropriate for light to medium production reaming in ferrous and non-ferrous materials where a straight-flute, right-hand cut is suitable. The compact 3.5-inch overall length is well suited to short-reach applications in drill press work, lathe tailstock setups, or CNC turret operations. The HSS construction provides adequate hardness and edge retention for general shop use without the added cost of carbide tooling. Sold individually with a minimum order quantity of one, it is a practical single-piece replacement for worn or broken reamers of the same diameter specification.

• HSS tool material provides good hardness and edge retention for general metalworking
• Straight-cylindrical shank for direct mounting in drill chucks or collet holders
• Bright, uncoated finish allows easy visual inspection of cutting edge condition
• 3.5-inch overall length suited to short-reach drill press and lathe tailstock setups

Compatibility

Designed as a standard chucking reamer for use in any drill chuck or collet holder accepting a straight-cylindrical shank at this diameter range; no specific model compatibility data was provided for this part.

Installation Notes

Chucking reamers are installed by machinists or toolmakers into a properly sized drill chuck or collet on a lathe, drill press, or machining center. Secure the shank fully in the chuck before operation and verify runout with a dial indicator before reaming finish-critical holes. Always ream at appropriate speed and feed for the workpiece material and apply cutting fluid to extend tool life and improve surface finish. Remove the reamer from the holder when not in use to prevent edge damage.
