Combination Chucking Reamers with Straight Shank

Schedule J1

Designed for general purpose machining, left hand spiral chucking reamers work best on through-hole or limited stock removal applications. The high helix design of our chucking reamers reduces chatter and vibration and provides for easier chip removal. Precision design provides for exceptional quality and accuracy in most materials. Ideal for use in lathes, drill presses, milling machines and machining & turning centers.

Chucking reamers are furnished as Left Hand Spiral, Right Hand Cut.  Also available in Right Hand Spiral or Straight Flute. Flute Diameters are held to a tolerance of +.0002"/-.0000" unless otherwise specified.

Helical Chucking Reamers can also be made as specials in extra length, larger diameters, special helix angles, end cutting, with chip breakers or in premium high-speed steel or carbide.
