Place the hinge in its mortise to see if it’s flush with door surface. Work from the knuckle side in until the mortise floor is flat.ĥ. Holding a chisel bevel-side up, with one hand on the blade and one on the handle, slice away any wood that the bit couldn’t reach. Without that reference, there’s no way to know when to stop drilling.Ĥ. Work methodically across and along the length of the mortise, always keeping part of the bit next to an untouched surface. Stop and drill again in an adjacent spot so the holes just overlap. Drill slowly until the line on the bit reaches the surface of the door. Place the bit square to the edge of the door and just inside the hinge outline. Can You Use a Forstner Bit in a Regular Drill Yes, you can use a Forstner bit in a regular handheld drill. Take a felt-tip marker and mark the bit using the edge of the hinge as a guide. Hold the edge of the hinge against the bit’s lower edge. Score this line deeply with a sharp utility knife.Ģ. Place the hinge on the edge of the door with the knuckles pointing in the direction the door opens and mark around its perimeter with a pencil. Select a bit diameter that’s about two-thirds the width of the mortise: Anything smaller takes too much time, and anything bigger requires more chiseling.ġ. You need a chisel only to clean up corners that the bit can’t reach. Here’s a way to quickly make hinge mortises using a Forstner bit and a cordless drill. Test the fit | Photo by Don Penny/Time Inc. If you've set your depth taking the template into consideration (see the end of step 1), then leave the template in position until you're finished drilling.5. Once you're about half the required depth you may remove your template and continue the drilling sequence until you reach the desired depth. I found out that slightly rocking the drill up and down while drilling makes the process go smoother. Might not be very accurate (may be some wobble) compared to in a drill press. Seems like the Forstner would be similar to those hole drills that electricians use, in hand-held drills.
#Forstner bit in hand drill full
Do not drive at full speed and at all times watch for over heating. Can a forstner bit be used in a hand-held drill, or should they only be used in a drill press Thanks. Drill small amounts on each hole in sequence. top and left), and again lay out your hardware and using your drill press make the holes all the way thru.ģ) Attach your template to the piece: align the reference corner of your template to your piece and clamp it making sure it won't move:Ĥ) Make the mortise: I always wax the sides of my forstner bit before starting the cut, this seems to help a bit with over heating by reducing the friction with the MDF template.
Important: If you're about to drill a very shallow mortise, you may consider setting your depth gauge with your template (see next step) applied to the test piece: once you drilled your template position it over the mortise on your test piece and grab that depth instead.Ģ) Drill your template: Grab a piece of 3/4" MDF, reference a corner to your piece (e.g. Make sure the mortise won't interfere with the screw locations. Hand drills cant be as tightly speed regulated as can drill presses, so constant attention to their speed is essential: in fact, though, its really best not to run Forstner bits in handheld drills, because of the lack of speed control (and accuracy-Forstner bits are made for clean, neat, accurate holes, which is seldom what a handheld drill. When it's time to drill both sides, only drill about an 1/8' in. Use the same 3/8' Forstner bit, make sure everything is lined up and either tap the bit with a hammer or you can do what I did and chuck the bit up in a drill press and 'press' the indentation. Then set and lock a depth gauge for future reference when drilling on your piece. I've included a picture showing the marking of each side of the relief window. Test your hardware until you get a nice fit. Unfortunately I don’t have a drill press, but also once the cutter enters the workpiece a guide like that wouldn’t keep the bit straight because the shank is. Then clamp it to your workpiece and use the block to guide the bit. Required Tools: Drill press, hand drill, Forstner bit, wax, chisels, 3/4" MDF, scrap material.ġ) Determine Forstner bit size and cut depth: Using your drill press, lay out your hardware and make a test cut on a piece of scrap to determine the right size of the fortsner bit, the location of required holes and the depth of cut. Get a chunk of 2x4 and drill a hole through it on a drill press with that bit. I've seen this question asked a couple of times on these forums, and since I had to do it again during the weekend, I figured I could explain my process here for those who may take advantage of it. Of course a woodworking router or hand tools will get the job done too, YMMV.
#Forstner bit in hand drill install
This is about drilling a quick mortise on a finished piece, in order to install hardware, using a hand drill and a Forstner bit.
