Description
Whether you’re fixing a broken plow bolt, drilling pilot holes for a new barn door, or making repairs in the shop, having the right drill bit makes all the difference. This 29/64 inch high speed steel bit is sized perfectly for those medium-duty drilling jobs that come up all the time around the farm. It’s that go-to size that’s not quite 1/2 inch but bigger than 7/16—exactly what you need when standard sizes just don’t cut it.
What You’re Getting
- High speed steel construction that stays sharp longer and cuts cleaner than regular carbon steel bits
- 29/64 inch diameter—perfect for drilling holes just under 1/2 inch when precision matters
- Works great in both metal and wood, so you don’t need separate bits for different materials
- Standard round shank fits any chuck on your drill press or hand drill
Built for Real Farm Work
This bit handles everything from drilling out broken bolts on your cultivator to making mounting holes in steel brackets. It’s also handy for woodworking projects around the farm—building gates, repairing barn doors, or making custom fixtures for your shop. The size makes it ideal for clearance holes when you’re working with 7/16 inch bolts or need a snug fit for dowel pins.
Made to Last
High speed steel holds its edge much longer than regular drill bits, especially when you’re drilling through tough materials like hardened bolts or dense hardwood. The steel can handle the heat buildup that comes with heavy-duty drilling without losing its temper or dulling quickly.
Good to Know
For best results in metal, use cutting oil or even a drop of motor oil to keep the bit cool and extend its life. When drilling wood, clear the chips regularly so they don’t clog up the flutes. If you’re drilling deep holes, back the bit out occasionally to let it cool down and clear debris.
