- Q:How do you drill a bit?
- A bit, including a cutter rod, a cutter rod tip, tip two is located in a main plane (C - C) on the cutting insert (5, 5 '), the cutting blades (5, 5') have in common second planes (E - E). The orientation of the short cutting edge center. The blade forms a point like center, the cutting edge is used to enter the workpiece, and thereby the bit is aligned. Two chip grooves (6, 6 ') are arranged on the cutter bar, and the chip removing slots (6, 6') extend from the tip to the end. In any section along the bar, the flutes are located are diametrically opposed to each other's position in the flat tube, flat tube and two common edge edge in the pipe on both sides of the belt plane (F F) 90 degrees extension, wherein the knife rod has a maximum in the rigid plane. The orientation of the second plane (E E) of the center cutting edge is approximately 90 degrees with respect to the main rigid direction (F F) of the blade plane or the bottom of the cutter bar.
- Q:How to distinguish between electric hammer drill bit used
- Use the hammer drill shank is square, drill shank is round. The hardware store that buys electric tools will find out in comparison.
- Q:What drills should be used to drill holes with diameter 5mm and depth 65mm? Urgent! Thank you!

- Q:What are the main points of drill grinding?
- The edge of the drill must swing up and down, and the tail of the drill can not stand up. This is a standard bit grinding action.
