💡 What makes a straight shank bit a handy go-to for weekend workshop runs?
- A steady ten to fifteen percent reduction in feed pressure prevents binder burn when transitioning from hardwood to soft steel alloys.
- Consistent downward force combined with medium speed settings helps maintain the cutting edge without generating excessive friction heat.
- Regular coolant application extends the service life of high speed steel tools when tackling dense metals or glued laminated lumber.
- Proper chuck tightening eliminates radial runout that causes crooked openings and premature wear on replacement bits.
