✅ Fits workpieces spanning 3/16 inch to five inches (5mm to 130mm) in diameter

💡 Why is a dedicated center starter handy for tackling stubborn alloys on the bench? These pre-drills lock onto the workpiece fast so you stop wasting material on crooked holes. - Rigid cobalt cores handle thermal shock while driving through chromium plates. - Angled lips slice through scale cleanly to leave perfect alignment marks. - Deep helix paths eject hot dust rapidly to keep the cutting edge sharp.
