The listed pairings are arbor 49-57-0030 with 4262-1 and arbor 49-57-0010 with 4292-1. Confirm the machine’s own instructions before assembly.

Keep clear of the ejected plug and stop rotation before clearing chips. Inspect teeth and drive engagement before the next cut.

Important Product Questions
Can I use a nearby arbor that appears to fit?
Verify the exact interface and the machine/arbor combination. Secure engagement, cutter depth and pilot-pin travel must all suit the setup; appearance alone is not enough.
Can I cut past the stated depth?
No. Choose a cutter with sufficient working depth for the stock. Do not force the body or shoulder beyond its designed cutting range.
How do I select the finished hole size?
Choose the actual required hole diameter. A bolt, pipe or fitting’s nominal size may require a different clearance opening; check the drawing or fitting instructions.
