Frequently Asked Questions

What is a YANKEE undersized spiral-flute cobalt chucking reamer used for?

This YANKEE reamer is used for precision hole finishing in metalworking, where a 0.249-inch diameter with 1/4-inch undersized cut is required. The spiral flute design helps evacuate chips, making it suitable for through-hole or blind-hole applications in ferrous and non-ferrous materials.

What are the specifications of the YANKEE 1435-0.2490 chucking reamer?

The YANKEE 1435-0.2490 is a right-hand cutting, spiral-flute chucking reamer with a 0.249-inch diameter and 1/4-inch undersized specification. It is made from cobalt material for heat resistance and durability. The manufacturer part number is 1435-0.2490.

Where to buy YANKEE chucking reamers worldwide?

3G Electric supplies YANKEE chucking reamers like the 1435-0.2490 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this cobalt spiral-flute reamer.

How to select the correct undersized reamer for a 1/4-inch hole?

For a 1/4-inch finished hole, select an undersized reamer like the YANKEE 1435-0.2490, which cuts 0.001 inch under nominal size. This allows for final sizing with a separate finishing reamer or burnishing. Always match flute type (spiral for chip evacuation) and material (cobalt for harder workpieces).
