6. RPENING When grinding drills in order to maintain the effi ciency of the drill extreme care should be exercised The dead center or point of the drill must be main tained that is the cutting lips must be of equal length See Figure 2 Also their angle must be the same in relation to the axis of the drill approximately 60 each or 120 included angle between the cutting lips for metal 35 each or 70 included for wood The metal should be relieved gradually behind the cut ting edge so that the included angle at the heel of the cutting lips will be approximately 12 on a side less than at the cutting edge itself OPERATION When the drill press is used for wood working it is advisable to fasten a smooth level auxiliary table of inch plywood to the metal table using counter sunk flat head screws or bolts This auxiliary table not only increases the working surface available but provides a surface on which auxiliary fences shaping guides pivot pins and other similar units may easily be used This auxiliary table also will minimize the danger of drilling through the work piece into the metal table If the drill is to pass completely through the work piece it is advisable to place a piece of scrap wood under the work piece at the point of breaking through to prevent splintering and mutilation of the lower surface as the bit breaks through Another method of preserving the surface at drill break through is to reverse th
7. bility to the feed return adjusting knob the handle positions may be changed without disturbing their locking efficiency By backing out the small slotted head set screws in the respective lock handles the handles may be removed from the heads of the hexagon screws on which they are engaged and rotated until their locked position no longer causes interference Reinstall the handle on the hexagon head of the screw and tighten its set screw In the same manner the table lock handle may be removed from its normal position and used on the hexagon head of the table tilt lock X 278 TYPES OF BITS variety of bits is available for use in your drill press The solid center wood bit has a single flute turning around a solid center but carries two spurs and two cutting edges The hollow spiral bit or ship auger is an excellent bit for drilling deep holes in wood Its design permits very efficient removal of chips necessary in deep hole drilling The hollow spiral bit has but one cutting edge The fluted bit is an excellent all around wood boring tool It has two flutes or twists each termi nating in a cutting edge and spur Perhaps the best bit for high quality machine drill ing in wood is the spur machine bit in a twist drill pattern It is a stiffer drill than any previously described tracks nicely and cuts an exceptionally smooth hole The twist drill while almost universally used for metal drilling with a 120 inclu
8. ded angle between the cutting lips is readily adapted to wood drilling by changing the angle to approximately 70 For larger holes the multi spur or rim type bit is often used This type bit generally has a single cutting edge with several spurs arranged as saw teeth around the rim The expansive bit is a handy drilling tool for large holes due to the variety of hole sizes which may be drilled without having to stock separate drills of large diameters not often used When the expansive bit as well as any of the pre viously described bits are used on the drill press the ecrew point should be altered to a brad point by removing the threads This will not impair the effi ciency of the bit and will prevent the coarse screw threads from engaging the wood and raising it from the table For use on the drill press the double lip style countersink is more desirable than the rosette type The double lip style will make a cleaner cut and will tend to remain more clear of chips and gum under continuous operation While high speed steel drills generally give more satisfactory service for commercial operation because of higher speeds possible and because they hold their edge longer their greater cost often makes their use in the home shop unwarranted Unless extensive metal drilling operations are planned the less expen HEEL OF CUTTING LIPS DEAD CENTER N sive carbon steel drills will give quite satisfactory results DRILL SHA

10. he angle fixed If the drill is long enough to go through the piece but its penetration is limited by the travel or feed limit of the chuck the piece may be set up on a block after the first cut of maximum feed depth has been made thus allowing the drill to penetrate to its maxi mum length Holes through a piece the thickness of which is greater than the drill length may often be completed by first establishing the location of the piece in rela tion to the drill center then after drilling as far as possible from one side the piece may be reversed and the hole completed from the other side All metal work should be clamped securely to the work table before drilling is attempted Should the drill lodge in a piece not clamped it could easily tear the piece from the operator s grip resulting in injury to the operator as well as mutilation of the drill press and work piece punch mark on the metal surface at the center of the proposed hole will tend to keep the drill on center until the drillspot is established Avoid set ups which will allow the work to spring This will help minimize drill breakage Lubricants should be used on all metals except cast iron which is drilled dry For most metals lard oil is a suitable lubricant for the harder metals a solution of sal soda in water may be used This drill press is designed to give maximum pro tection from moving parts at all times Since a guard on the chuck and drill would

14. otor pulley and the smallest step on the spindle pulley are used When using the next step down on each pulley the resulting speed will be approximately 2450 R P M A speed of approximately 1250 R P M can be attained by mov ing the belt to the third step from the top on each pulley The lowest speed available 625 R P M may be obtained by placing the belt on the smallest step of the motor pulley and the largest step of the spindle pulley Other speeds are attainable by changing the position of the motor pulley in relation to the spindle pulley so that further step combinations are created Due to variation in the bit pattern the type hard ness and grain of the material and the depth and quality of the hole desired it is impractical to attempt to establish a fixed table of drill feeds and speeds for boring in wood It is best to follow this general rule the larger the hole and the harder the material the slower the feed and speed An approved method is to start any drilling operation with a moderate feed and speed increasing either or both after noting the effect on the drill In wood drilling operations drills up to 34 inch in diameter may generally be run at 1800 to 3000 R P M without burning while bits 34 inch in diameter or over cannot generally be run over 2400 R P M without burning Multi spur bits expansive bits and hole saws should never be operated over 750 R P M In general if the drill smokes in the hole reduce
15. the feed and speed to prevent burning When drilling metal if it is noted that the drill wears away at the extreme outer corners of the cutting edges it is an indication of too much speed Likewise if the drill chips on the cutting edge it is an indication of too heavy a feed Very small drills are generally designed for high speed and light feed and should be used accordingly for best results Always reduce the feed pressure when the drill is breaking through the surface of a work piece This reduces the tendency of the drill to bite deeply at this point and thereby minimizes drill breakage CHUCK The jaws of the chuck may be adjusted to hold drills up to inch shank diameter by using the key 18129 provided The key should be inserted in one of the holes in the chuck shank so that the teeth of the key and of the chuck mesh In this manner the jaws may be opened by turning the key counter clockwise and closed by turning the key clockwise CONTROLS The chuck may be lowered approximately 4 inches by turning the pinion shaft counterclockwise For this purpose the feed levers or feed handles Figure 1 are provided The feed mechanism in corporates an automatic spring loaded return action The feed stop nut Figure may be used when two or more holes must be drilled to the same depth or when the depth of a blind hole must be set before drilling The feed stop lock nut acts as its name indicates to lock the feed stop nut in pos
