3/16" x 1" Chipbreaker Compression - 1/4" Shank - CM281CB

The 3/16" Chipbreaker Compression Bit is the go-to choice for medium-thickness hardwoods, plywood, and laminates. Ideal for profile cuts, pocketing, and small-to-medium projects, this bit combines precision and efficiency. Its unique upcut/downcut flute design pulls chips toward the center, delivering clean top and bottom edges with virtually no tear-out or fuzzies — perfect for hobby and production CNC users alike.
