Product Description
Milwaukee Spline 4-Cutter Bit 2 in. x 22 in.
Model Number: 48-20-4419
The Milwaukee 48-20-4419 is a Spline drive 4-Cutter Bit in 2 in. diameter with a 22 in. overall length — a large-bore extended-reach rotary hammer bit for the Spline drive platform's highest energy output, delivering four-cutter tip performance at the maximum standard bore size for the deepest structural penetrations and anchor embedments in the hardest commercial concrete. The Spline drive platform's substantially higher impact energy output than SDS Max and SDS+ makes it the appropriate choice for 2 in. diameter drilling where the enormous cutting face resistance in hard aggregate requires every available unit of impact energy for productive penetration rate. The four-cutter tip provides four active carbide cutting contacts per revolution, maintaining drilling momentum through the hardest aggregate that would completely stall two-cutter bits at this massive 2 in. bore in dense commercial concrete.
At the 2 in. large bore and 22 in. working length, the flute geometry must manage the substantial chip volume generated per revolution through the full extended working depth — the Spline 4-cutter bit's flute design addresses both the high chip generation rate of the four-cutter tip and the extended evacuation path of the 22 in. configuration. The 2 in. diameter at this length serves the largest structural core anchor applications, major conduit bundle through-wall penetrations in thick foundations, and the most demanding commercial structural drilling specifications where this bore size and working depth are simultaneously required. The Spline shank provides the positive anti-rotation locking and maximum energy coupling of the Spline drive system.
