You need to state your problem in a little more detail. What size is
the hole? What kind of equipment do you have to drill with? What kind of finish does it need? Bugs |

Do you have a means to adjust your work in a vise at a 45 degree angle or
does your drill press/mill head cant to a 45 degree angle? How long is the work piece? If the piece is too big to chuck up in a vise then you will have to make some kind of fixture to attach to the pipe to maintain your angle. Need more input before I can decide how I would drill the hole. What tools do you have to work with? How accurate does the angle need to be and how accurate does the angle need to be?

Assuming this is a full joint of pipe, 21 feet long, I would use a file
to make a little 45 degree notch so the drill bit will not wander. Then make a jig to hold the drill at 45 degrees and centered on the pipe. I would make the jig for about an 1/8th inch drill as well as for your 1/4 inch drill. I would then drill through one side of the pipe with the 1/8 inch drill. THen I would figure out where the exit ought to be on the other side and file a notch there. Then move the jig there and drill an 1/8 inch hole. Then I would use a 1/8th inch aircraft drill to go in from one side and out the other. Probably repeat with a 3/16 th inch aircraft drill , before using the 1/4 inch drill to go thru the pipe.

Start the hole squared on and then after you get down to where you have a
few thou of wall, work the drill over to the 45 deg. angle while it is turning. The alternate is to make up a block that will guid the drill at the 45 deg. angle and clamp that where you want to drill the hole. There are drill guide inserts that will keep the block from being chawed up available. -- Why isn't there an Ozone Hole at the NORTH Pole? |

Start a straight hole until the flute tips are flush with the surface.
Tip the drill slowly 45° and procede. JR Dweller in the cellar Simon Mustey wrote: I want to drill a hole on a 1/4 inch 45 degree hole through the centre of a peice 1.5 inch shed. 40 steam pipe.
