Next we illustrate the main parts comprising a bit and we define each one. Main parts of a bit 7 8. Shank. End shaft of drill bit by which it is fastened onto the chuck. The shank may be straight, tapered or reduced, as shown.. Flute length. The drill bit s cutting portion with a fluted pattern, from the shank s end to the tip. The helical spiral design is standard in this product line. STRAIGHT SHANK Spiral type Materials Allows the drill bit to be attached onto all types of keyed and keyless -jaw chucks found in stationary drills. Slow Spiral Fibrous materials such as rigid plastics, asbestos, etc. REDUCED SHANK Straight shank, usually reduced to /, allowing drill bits with large diameters to be attached to conventional -jaw chucks without the need for a greater capacity chuck. Standard Spiral For standard industrial operations (wrought iron, carbon steels). MORSE TAPER SHANK For industrial applications requiring strength, precision and steadiness when drilling (stationary tool, numerical control, etc.). This shank is designed to absorb the torque generated during the drilling process. Fast Spiral Soft materials such as aluminum, magnesium, copper, wood, plastic. CUTTING & GRINDING TOOLS. Surface area. It is the surface area that is ground when a drill bit is sharpened. During the cutting process this part should not come in contact with the drilled piece. This is coonly known as shaving and it takes place on the contacting surface as well as on the drill bit diameter. 7. Lip relief angle. Angle formed by the intersection of each flute s land surface area. This angle determines the helical bit cut. SUPERIOR QUALITY AFFORDABLE TOOLS Order from MARYLAND METRICS P.O.

They break up burr from the hole s bottom and are ideal for machinery with numerical control.. Helix angle. This angle combined with the centrifugal force generated by the bit s rotational motion allows the burr to be smoothly pulled out.. Point angle. The most coon angle is 8, however it may vary in those for specialized applications. If soft and non-ferrous materials need to be drilled it is better to increase the angle to. When working on materials with a hardness higher than steel, decreasing the angle is recoended. 7. Flute. The helical grooves on the bit around which burr travels up and outside the hole when drilling. 8. Cutting edge. It is the surface area s front edge. The drill bit has two cutting edges, one per helical flute. Under normal conditions a continuous flow of burr signals proper sharpness. However, when this burr starts coming out in small chunks it means the bit has to be sharpened, and if it is not then it may start screeching. If the user continues using it like that it may overheat and end up breaking. BIT COATINGS Black Oxide. Creates a thin black layer that reduces friction and increases lubricant retention. Drill bits with this coating are recoended for drilling steel and not for non-ferrous materials because burr tends to stick to it. Nitride and Oxide. They combine the advantages offered by oxide with lubrication and nitride with resistance to abrasion.

Tips with cutting edges do not guarantee correct centering and may easily deviate from a straight path when they encounter hard materials or rebar.
