6 drill bits necessary for woodworking
Since the era of drill bits and supports, woodworking has made great strides. Although we might romanticize those times, the limited choice of bits means that craftsmen usually choose holes that are "good enough". Today, we can choose professional woodworking series drilling bits, many of which can drill clean and tear-free holes, while others can drill holes with special shapes, which woodworking could not do long ago. These drill bits meet most of today's carpentry needs.
Bra point.
Under the guidance of the central point, these bits resist lingering. Sharp horns or spurs, cut cleanly on the texture, eliminate tearing and create holes with clean sidewalls. Deep grooves can quickly remove chips. You will find that the diameter of these drills range from 1⁄8" to 1".
Foster's bit.
To drill flat-bottomed holes, overlapping holes to create mortises, or partial holes that extend from the edge of the board, use a Forstner drill bit with a center distance to ensure an accurate start. The sharp rim produces a clean edge, and a knife that forms an angle between the burr and the rim plane can remove waste. Due to the large amount of chips, they will occasionally retract the drill bit from the hole when drilling to remove the chips and reduce the chance of bit sticking or overheating. These drill bits may have smooth or jagged edges, ranging from 3⁄16" to 4" in diameter. A drill bit larger than 3⁄8" is used in the drill press to control the rotational torque generated by the large cutting surface.
Conical and countersunk holes.
Very suitable for drilling pilot holes for screws, they create a hole and a groove for the screw shank, so that the screw head is flush with the wood surface, or countersink as needed. Adjust the collar around the drill bit up or down to match the length of the screw. Find a drill bit that matches the size of #4–#12 screws.
Self-centering drill bit.
The spring-loaded hand piece is sized to fit the screw hole on the hinge leaf, and retracts when drilling to center the guide hole. This ensures that the hinge screw is completely fixed in the countersunk hole of the blade, and the hinge will eventually reach the desired position. The drill bits used for #4, #6 and #8 screws proved to be the most useful.
Distorted bit.
Wandering to any woodworking series drilling bits workshop, you will find the common twist drill, which is a practical tool for drilling. Available in hardware stores, this versatile drill has a 118° tip and can drill into wood, plastic, and metal. Because the cutting starts from the center of the tip and moves to the outer edge, the wood fibers around the hole will be torn.
Shovel position.
Although not normally used in furniture manufacturing, these drills have a short job of drilling holes in construction-grade timber projects. Similarly, a central point guides the drill bit, and external thorns reduce tearing at the edge of the hole. Find these from 1⁄4" to 11⁄2" in diameter. Back up material when drilling through holes to reduce bursting when the drill bit exits the board.
