Wood drill bits Spade - expanded brad point tip with angle spurs for a cleaner hole and a distinguishable spike. The straight drilling tip at the center of the three-point product can stick into the wood like an awl.
With fast speed for boring hole, the product is often applied for processing hole with low requirement to machining accuracy and thin sheet needing to be pierced.
Regularly, the wood flat drill bit comes with the outer diameter ranging from 6mm to 40mm, material of 45# steel and the hardness from HRC40 to HRC48.
The Forstner product is especially used for processing hole with high precision and flat-bottomed hole.
The single spur cuts and defines the edge of the hole while the chisel-like cutting edge removes the waste within the previously cut circle.
The normal twist drill head would slide to other place easily when boring hole on flat processing surface. The type with fine pitch thread is fit for hand drill to process the cork wood and wet wood. We offer variety of products, including masonry drill bits, taps for screw thread, diamond saw blade, HSS tool bits, and much more. So, during the drilling process, a guide hole is often bored for positioning the drill head.
Featuring good machining accuracy and excellent processing effect with good smooth finish and little burr of hole, it can also be employed for processing counterbore. Generally, the common type three-point wood drill head is processed through rolling, while the high precision one is processed through milling. When using the product, the user needs to push the product hard to make it deep into the wood material.
