Frequently Asked Questions
A helical bit that lifts chips upward, ideal for deep plunges and fast chip evacuation.
Use up-cut for deep pockets and efficient chip removal; choose down-cut when you need a splinter-free top face.
Some top-side splintering can occur; minimize it with a backer board or shallow first pass.
Excessive RPM or slow feed causes heat; sharpen or clean the bit and speed up the feed.
Clear chips with strong dust extraction or pause to vacuum; up-cut flutes already help eject debris.
Compression bits give splinter-free faces on both sides; up-cut is faster but may fray the top veneer.
Extra flutes can improve finish but require slower feed per tooth; 2-flute is a good all-round choice.
Too-deep cuts or slow chip evacuation overheat the small shank—use shallower passes and higher feed.
They’re fine if feed direction is correct and stock is clamped; expect more chip spray than in a table.
Use sharp bits, minimize tool overhang, and match feed to RPM to keep chip load steady.
