💡 What drives the best feed rate when using high speed steel twist drills on mixed materials?
Dialing in your spin speed pays off big time when you want those holes round and true without warping the stock. Here is how to run them smooth:
- Back off the throttle on thick hardwood slabs so the carbon steel core stays cool
- Pick up the pace on brittle fiberboard and soft plastic to avoid grabbing edges
- Align the tip dead center against the layout mark before pressing the trigger
- Feather the trigger for steady bites instead of stomping down hard on the handle
