Review on HQMaster 3 175Mm Straight Milling Tungsten by Jerry Chembola

This is a good nozzle with some specializations. Run this on a Shapeoko with a Bosch 1617. Perform at 100 ipm with a 3/8” DOC at full speed. Works very well with thin plywood (1/4 inch) as you don't need tape to hold the board in place as the cutter doesn't pull up like with spiral grooving. On thicker materials like 3/4 inch barrier ply you get a layer of pressed sawdust holding the piece in place which makes cleaning a bit tricky as in some cases a screwdriver is required to get the dust off the cut separate but the edge quality is very good Lifespan is a little short as with most HQMaster bits, sometimes the bit will last around 10 hours of straight cutting before you notice any signs of dulling (rougher edges, more RPM loss when cutting etc.) and sometimes break them.
