Explaining a Drill Press(DP) goes without saying that this instrument has a lot of variables that contribute to the full function and precision. Generally it can be described as a drill head mounted on a column which can in turn be fixed on some immovable object for example: a work bench. This drill head can be moved on up , around the column as required by handles. Since the drill axis is fixed and do not deviate due to jerks (which happens in a normal handheld drill), it can give a very precise cut or bore in the intended object.
What is a Drill Press used for?
The precision, functionality and a lot of other factors of it has not only made it popular with a lot of woodworkers and metal workers but it has become an absolute must have, of course with nature of work with most of them.
Woodworkers find it really suitable to drill precision cut bores out of a large plank or even a thick one since this drill can be set to create precision cut repeatable holes which is a painstaking task if a handheld drill was used in its place. This is because of the fact that the drill’s fixed head in combination with the adjustable table maintains the precision factor between the rotating drill head and the material to be cut. Fine tuning a DP for precision jobs is another point which makes it so much more important to the user over normal drills. Also rotating speed can also be decreased as needed as speed of rotation of the drill should be lowered when steeping up the drill size. For metal works , heavy duty DP are used which generally consists of a powerful motor and upgraded parts needed for the consistency and durability.
Deburring a hole
After a hole is drilled often times it is needed to deburr it. Generally the top side of the hole is clear but the bottom part may still have some burrs. Deburring a hole with it is easier since less effort is required and just needs the attachment of a deburring tool and a minimal pressure required after putting it inside the hole.
Generally a hole is precise enough but in case where the precision needs to be much more than two thousands of an inch in diameter (for example: in case of slip fits and interference fits), a reamer can be used. For this, the drilled hole must not be drilled fully and should be a little bit undersized initially. After this a reamer should be driven down with a constant and slow speed for achieving the desired result.
Tapping a hole
Often times it is required to cut threads inside a hole. This job is more preferably done by a DP rather than using any other kind. The reason is: the taps, dies are very brittle and hard in nature. Since this operation needs a lot of precision and measurements and the it can maintain its alignment as you tap the hole, it is just the most preferred candidate for this kind of work.
The accuracy, power, speed, versatility, functionality and safety offered by a DP far exceeds other types of drilling mechanisms making it a suitable choice of most wood and metal workers.
