TROUBLESHOOTING GUIDES FOR DRILLING AND TAPPING! DRILLINGTrouble Possible Cause CorrectionDrill Breaks Spring or back lash in press or work • Test press and work for rigidity and alignment Too little lip relief • Regrind properly Speed to low in proportion to the feed • Increase or decrease speed Dull drill • Sharpen drill Possible chip congestion • Peck drill

Outer Corner Uneven hardness in work material • Reduce speedBreakdown Too much speed • Reduce speed Improper cutting compound • Use proper cutting compound

Drill Breaks in Chips clog up fl utes • Increase speed. Use drills designed for these materialsBrass or Wood

Cutting Lips Chipped Too much feed • Reduce feed Too much lip relief • Regrind properly

Cracking or Checking Heated and cooled too quickly • Warm slowly before using. Do not throw cold water on hot drill while in Cutting Edges grinding or drilling Too much feed • Reduce feed

Hole too Large Unequal angle or length of the cutting • Regrind properly edges or both Loose spindle • Test spindle for rigidity

Only One Lip Cutting Unequal length or angle of cutting lips, or both • Regrind drill properly

Drill Splits up Center Too little lip relief • Regrind with proper relief Too much feed • Reduce feed

Rough Hole Dull or improperly ground drill • Regrind properly Lack of lubricant or wrong lubricant • Lubricate or change lubricant Improper set-up • Check set-up Too much feed • Reduce feed

Type Performance Benefi ts* Comments• General purpose• Widely available• Acceptable drill life• Best suited in mild steel and aluminum

• Self centering• Excellent for portable drilling• Longer drill life• Good for drilling on curved surfaces• Improved penetration rates• Requires less effort• Breaks up chips• Best suited in alloy steels

Conventional Point (118°)

• Not self-centering; “walking” can occur on hard surfaces• May produce burs on breakhrough

• Diffi cult to regrind

Split Point (118° and 135°)

*Depends on application

Deep Hole Drilling• When the hole depth is greater than three times the diameter, consider it a deep hole.

• Step drilling, also called “peck” drilling, is the practice of drilling a short distance, then withdrawing the drill. This is often required to remove chips when drilling deep holes.

• “Peck” drill just enough to prevent packing chips in the fl utes.

• Chip congestion (eg: chips clogging the fl utes) is a major cause of drill failure.

General Drilling Considerations• Stability is important. Instability can cause drill breakage of poor hole quality, including irregular or oversized holes.

• To prevent work hardening, pay attention to speeds and feeds. Feed pressure should be constant. Do not “peck” until half-way through a deep hole. Use moderate speeds and a variable drill motor if possible.

• To prevent lock-up (grabbing of drill by material or workpiece at breakthrough), ease through the material by reducing speed and feed.

X .26ShankThe part of a drill by which it is held and drivenSizeMeasurement reference for diameter size of a drill, expressed as either fractional, wire, letter or metricSpeedThe speed of a drill is determined by the rate which the outer edge of the tool rotates in relation to the material being cut. In general, the SFM is within a range based upon the workpiece material, its condition, hardness and depth of the hole. The deeper the hole, the greater tendency for more heat to be generated. Speed reduction is often recommended to minimize the amount of heat. It is usually best to start drilling at a slower speed and then increase.Split PointA special point confi guration that eliminates “walking” so holes stay on centerWebThe central portion of the body that joins the lands.

Black Oxide Black oxide is the most basic surface treatment recommended for drilling in iron and steel. It is not recommended for drilling in aluminum, magnesium or similar materials.

Drilling with a black oxide treated drill provides: • Increased tempering and stress relieving • Reduced galling and chip welding • Increased retention of lubricants

TiN CoatingTitanium Nitride (TiN) performance coating can increase tool life and productivity by allowing higher speeds and heavier feeds. It is an excellent general purpose coating for protecting tools from wear. TiN coating is an excellent choice for drilling in iron and steel. It is also recommended for drilling in aluminum, magnesium or similar materials.

Drilling with a TiN coated drill provides: • Increased surface hardness • Reduced coeffi cient of friction • Increased corrosion resistance • A thermal barrier • Additional tempering and stress relieving

Chamfer Styles in Standard Taps

End Views

Angle of ThreadThe angle included between the fl anks of the thread measured in an axial planeBack TaperA slight axial relief on the thread of the tap which makes the pitch diameter of the thread near the shank somewhat smaller than that of the chamfered endBottoming ChamferThe shortest chamfer (1-2 threads long) for threading close to the bottom of blind holesChamferThe tapering of the threads at the front end of each land of a tap, by cutting away and relieving the crest of the fi rst few teeth, to distribute the cutting action over several teethChamfer ReliefThe gradual decrease in land height from cutting edge to heel on the chamfered portion, to provide clearance for the cutting action as the tap advancesChordal Hook AngleThe angle between the chord passing through the root and crest of a thread form at the cutting face, and a radial line through the crest at the cutting edgeCrestThe top surface joining the two fl anks of a thread. The crest of an external thread is at its major diameter, while the crest of an internal thread is at its minor diameterCutting FaceThe leading side of the land in the direction of rotation for cutting on which the chip impingesFlutesThe longitudinal channels formed in a tap to create cutting edges on the thread profi le, and to provide chip spaces and cutting fl uid passagesHeight of ThreadThe distance between the crest and the base of a thread measured normal to the axisLeadThe distance a screw thread advances axially in one complete turn. On a single lead screw or tap, the lead and pitch are identical. On a double-lead screw or tap, the lead is twice the pitch, etc.

PitchThe distance from any point on a screw or tap thread to a correspond-ing point on the next thread, measured parallel to the axis. The pitch equals one divided by the number of threads per inchPitch Diameter• On a straight thread, the diameter of any imaginary coaxial cylinder, the surface of which would pass through the thread profi le at such points as to make equal the width of the threads and the width of the spaces cut by the surface of the cylinder

• On a taper thread, the diameter at a given distance from a reference plane perpendicular to the axis of an imaginary co-axial cone, the surface of which would pass through the thread profi le at such points as to make equal the width of the threads and the width of the spaces cut by the surface of the conePlug ChamferThe most common chamfer (3-5 threads long), for hand or machine tapping in through or blind holesRakeAny deviation of a straight cutting face of the tooth from a radial line. Positive Rake means that the crest of the cutting face is angularly advanced ahead of the balance of the face of the tooth. Negative Rake means that the same point is angularly behind the balance of the cutting face of the tooth. Zero Rake means that the cutting face is directly on the center lineSpiral Point (Chip Driver)A supplementary angular fl uting cut in the cutting face of the land at the chamfer end. It is slightly longer than the chamfer on the tap, and of the opposite hand to that of rotationTaper ChamferA long chamfer (8-10 threads long) for easier starting and engagement in the work piece. More working teeth means that less tapping torque is required, and the chip load is reduced on each toothThreads Per InchThe number of threads in one inch of length

Tapping SpeedsProper tapping speeds are very important in obtaining effi cient tapping results. The optimum speed for tapping is the highest speed that conditions permit, consistent with acceptable tool life. Speeds must be lowered as the length of the hole increases. In short holes, taps with tapered chamfers can be operated faster than taps with bottoming chamfers. Speeds can be increased when vertical tapping, as compared to horizontal tapping.

The chart below suggests a starting point for selecting the speed to operate the tap.
