carbide drill bits safety rules

⒈ in operation, please wear good clothes, safety glasses, hard hats, etc; please do not wear loose clothes and yarn gloves, to avoid danger.

⒉ to prevent iron hand scratched, use hooks to remove iron when carbide sds plus hammer drill bits .

⒊ Before using, check if there are injuries carbide drill bits, if injuries do not use.

⒋ If the carbide sds drill bit is stuck, turn off the motor immediately.

⒌ replacement, when removing the carbide drill bits, make sure that the device power is off.

⒍ when rotating the carbide drill bits, do not touch, to avoid danger.

⒎ carbide drill bits blade portion is very hard, but also very brittle, please be careful to protect, if the carbide drill bits chipping will affect carbide drill bits results, it can cause the bit to break.

The work principle of carbide drill bits

carbide drill bits is used for carbide drill bitsing in solid material out through holes or blind holes, and is able to existing hole reaming tool. Commonly used mainly twist carbide drill bits, flat carbide drill bits, center carbide drill bits, deep hole carbide drill bitsing and core carbide drill bits. Reamer and countersink carbide drill bits for metal, although not in the physical material carbide drill bitsing, but the habit will also carbide drill bits them into a class.
When the digging operation, the carbide drill bits bit rotating about a vertical axis, while for axial movement. The soil is cut in torque and axial force carbide drill bits role was destroyed in the extrusion and the centrifugal force of the blade work and pounding broken loose, flowing pressure to form a soil pit wall, while the elevator to the surface of the page. When the earth moves to free Pit stop the flow at the time, due to the centrifugal force pulverizer was thrown around the pit, to complete the digging process.
A carbide drill bits, comprising a shank ⑴, Arbor has a tip, the tip has two cutting insert in a main plane (C-C) on the (5,5 '), the cutting insert (5,5') having a short center on a second common plane (E-E) in the orientation of the cutting edges. Said blade forming a cutting edge for the center point into the workpiece, and thereby the carbide sds drill bit bit alignment. On Arbor, located two flutes (6,6 '), the flute (6,6') extending from the tip end in the end. Any length along the surface of the holder, the flute in the tube plane are located diametrically opposite positions to each other, the tube flat blade with two edges together with duct tape on both sides of the plane (F-F) to 90 ° extension, said shank having maximum rigidity in the plane. A rigid bottom of the main direction of the center of the cutting edge of the second plane (E-E) and the orientation of the blade with a flat or arbor (F-F) of approximately 90 ° angle.
