Hertel MR34-0181.099 Chucking Reamer 0.46mm Solid Carbide

Product Description

The HERTEL MR34-0181.099 is a solid carbide chucking reamer engineered for precision hole finishing in tight-tolerance applications. With a 0.46 mm reamer diameter and a reamer diameter tolerance of 0.0000 to +0.0003 mm, this tool delivers the dimensional accuracy required for critical bore work. The spiral flute geometry promotes smooth chip evacuation, while the bright polished finish reduces friction and helps maintain bore surface quality. At 50 mm overall length with a 2.5 mm flute length, this is a compact instrument suited for shallow finishing passes in hard, abrasive, or difficult-to-machine materials where solid carbide outperforms HSS alternatives.

This reamer is intended for use in CNC machining centers, drill presses, and precision lathes where chucking-style straight-shank tooling is standard. It is well suited for tool and die work, mold making, medical device manufacturing, and aerospace component finishing where sub-millimeter bore accuracy is non-negotiable. The right-hand cutting direction paired with left-hand spiral flute geometry helps pull chips away from the cutting zone, making it a common choice for blind and through-hole finishing in harder workpiece materials.

Key Features

• 0.46 mm reamer diameter with tolerance of 0.0000 to +0.0003 mm for tight-tolerance bore finishing
• Solid carbide construction for rigidity and wear resistance in abrasive or hard materials
• Spiral flute design with left-hand spiral direction promotes chip evacuation during right-hand cutting
• Bright polished coating reduces friction and supports consistent surface finish
• Straight shank for direct compatibility with standard collets and chucks
• 4-flute configuration balances material removal rate with bore quality

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank collets and chucks on CNC machining centers, drill presses, and precision lathes requiring sub-millimeter bore finishing tooling.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or tooling technician. Secure the straight shank firmly in a precision collet or chuck, verifying runout before commencing a cut, as excessive runout at this diameter will immediately affect tolerance and surface finish. Always confirm spindle speed and feed rate against the workpiece material specifications before cutting. Handle solid carbide tooling with care to avoid chipping the cutting edges during storage and setup.
