For any project that involves working around wood, and which calls for home remodeling or repair, a hole-saw is undeniably necessary. A hole-saw is a large diameter, hollow drill equipment that drills through wood, tiles, wall studs or even floor jots. With this tool, you have the assurance that working with various workpieces, imperatively wood, is made a whole lot efficient. Just like other woodworking tools, basic skills are learned on how to handle the saw. Precisely why we are here to assist you by enriching you with a skill set and have the right approach towards using a hole-saw.
How to Use a Hole-Saw
A proper setup
- When handling a hole-saw, you need to prepare a proper setup.
- Mount the appropriate size of the hole in the pilot drill bit.
- If the center bit of the hole-saw is adjustable, ensure that it protrudes beyond the teeth of the saw approximately 3/8 inch.
- Affirm the hole-saw in the corded 3/8 variable speed drill.
Contact is crucial
- Run the drill of the saw slowly and steadily for the teeth at the edge of the saw to remain in contact with the workpiece.
- The drill has to be positioned perpendicularly with the workpiece. The drill should remain in contact with the workpiece from the beginning.
How to Properly Use a Hole-Saw
Bore a pilot hole
A pilot hole leads the larger drill to the exact position of the drill.
- Mark out the middle of the hole.
- Drill a 1/8 inch pilot hole completely through your workpiece.
- Observe the bit level and let it be perpendicular to the workpiece.
- Align bit for full contact.
- Run the drill gently until the teeth are in contact with the piece of work.
Line up center bit with the pilot hole.
- Run the drill steadily and gradually until the teeth of the saw have contact with the workpiece.
- Ordinate the center position with the pilot hole.
- Hold the drill true heartedly with both hands for a saw with a side handle.
- Raise the speed of the drill and apply pressure by pushing in after the saw has cut the 1/8 inch deep circular groove.
- Ply the drill at high speed.
- Slower the speed periodically to allow the sawdust to fall off from the groove. Moreover, this cools the drill making it easier to handle.
Finish the Hole
- After drilling the pivot hole halfway through the cut on one side, shift to the opposite side and drill the same.
- Align the drill with the pivot hole
- Complete the hole by regulating the speed of the drill as instructed in the above steps.
- The wood plug will attach itself to the edge of the saw's teeth and pop out from the opposite end.
Most workpieces end up being splintered after the drilling process, however, we can evade this.
- Clamp a scrap board to the opposite side of the hole.
- Drill a pivot hole through one side.
- Finish drilling through from the other end.
- Shift to the opposite end.
- Clamp the board on the side you have shifted
- Repeat the process after clamping.
Reducing strain on the wrist
Drilling holes can be very tedious so a strain-free method is advisable.
- Drill 3/16inch closely spaced holes around the perimeter of the targeted hole.
- Drill 1/8 inch pilot holes.
- Finish your cut by aligning your drill with the arbor then steadily increase the speed of the drill until the circular groove is made.
Enlarge Existing Holes
The pivot hole only acts as a guide for the large drill to the appropriate position of the cut. Therefore, the arbor does not play a fundamental role in enlarging the hole.
- Mark out the point of the exact middle of the cut.
- Clamp a piece of scrap wood over the hole.
- Mark also the center positions on the wood.
- Now place the arbor on the center marks.
- Drill through the scrap wood and workpiece
Chisel out The Core for the Deep Holes
Extracting wood plugs has turned out to be a major complaint in holes saw drilling but this problem is avoidable. Pry out the plug with a chisel.
You can chisel out the plugs as you continue drilling, as a result, the hole goes deeper.
Even as you continue to drill remember to withdraw the drill occasionally to help in clearing out the sawdust.
Required Tools For This Project.
- Clamp- used to cover the sides of the holes to prevent splintering and facilitate the enlarging of the hole.
- Wood Chisel- used to scrape off the remaining wood plugs in the groove.
- Hole-Saw Kit- has quick-change, large and small mandrels plus replacement parts.
- Corded drill- an electrically powered drill.
- Earplugs- used to protect you from unpleasant noise.
- Drill bit Set- Contains a set of drills.
- Safety glasses- used to prevent wood particles from penetrating the eyes.
- Tape measure- used to record measurements.
Required Materials for This Project
The saw teeth are operated for most materials such as metal, plastic, wood and soft plaster. For this guide, we have discussed most tips for woodworking. The hole-saw can also drill holes into other tough abrasive materials such as concrete, tile. For abrasive drilling, the hole-saw is rimmed with super sharp carbide or diamond pieces.
Final Verdict & Recommendation
I suggest that if you are up to any home improvement plans, keep purchasing a hole-saw in mind. The hole-saw drills through workpieces quickly and cleanly. The cuts have a large diameter, making it suitable for manipulating it as a hand tool, plumbing tool, and power tool. It comes with convenient sizes depending on the task at hand.
Having a hole-saw spark in you the need and passion to be handy around things professionally or for DIY. This subsequently improves your self-sufficiency. I love the aspect that the hole-saw does not have to cut up through the workpiece which guarantees a smooth damage-free process. Saws with a side handle give you a firmer grip and are affordable.
