Important Product Questions
Which punch-and-die sizes are included?
The official contents list includes 7/8 and 1-3/8 in sink punches and dies, 3/8 and 3/4 in ball-bearing studs, and 5/16 and 1/2 in cobalt drill bits.
What stainless thickness is supported?
The product page rates the sink-punch setup for up to 16 gauge stainless steel. Verify material and setup before cutting.
What helps in a confined space?
Milwaukee specifies 5° ratcheting action, allowing the ratchet to advance with a short swing. Leave enough clearance to keep the setup aligned and your hands safe.
