When it’s time to bore a hole, a drill bit attached to the end of a power drill is often the most effective method. Bits will need to be chosen to match both the job and the substance. While there are special kinds that don’t fall into traditional measuring criteria, most are created in either standard or metric dimensions. Most bits are utilized to create round holes, but a number of the special ones produce various shapes.
The most common type in use today is that the spin piece. It may be used to bore holes in wood, metal, and plastic based on the angle and fluting of this piece. Twist bits are generally available in many sizes, from the very small ones with a diameter of about two thousandths of an inch to those who have a diameter approaching four inches. Lengths for home use can reach nearly forty inches.

Center pieces often are used for metals to create a starter hole which will be drilled using a bigger bit. However, the true intention of center pieces is to produce an indentation for a lathe. Spotting pieces are actually the preferred option for starter holes.
When the job calls for enlarging a hole which already exists, center or reamer pieces may be used. The choice depends upon how much the hole has to be enlarged. Reamers should be utilized when only a small increase is required, while cores should be used when considerably more material has to be removed.
A brad point or dowel bit is exactly the exact same thing, and these are sometimes called lip and spurs. They are generally chosen for use on plastic and wood. They’re cousins of the spin style, but might create a neater hole. A twist bit can capture and pull fibers, leaving a messy hole.
Paddle or spade bits are often used with wood, even though they can cause splintering when leaving. They’re made almost entirely for hand drills. Woodworkers often prize them since they can create a neater hole than many spin pieces.
