Application of tapered drilling tools
Tapered drilling tools are commonly used in a variety of applications for drilling holes of different sizes and depths. They are particularly suitable for drilling holes for explosives or anchors in the mining and construction industries, as well as for drilling holes in the oil and gas industry.
Tapered drilling tools are also used in woodworking, metalworking and other manufacturing processes that require precise and efficient drilling. They are often used in combination with other drilling tools, such as twist drills, to create pilot holes or enlarge existing holes.
In addition to drilling, tapered tools can be used for reaming, countersinking and chamfering, providing a versatile tool for many different applications.
Why are tapered drilling tools tapered?Tapered drilling tools
are tapered because this shape has several advantages when drilling into materials.
First, the tapered shape makes it easier to start and guide the tool into the material being drilled, making it less likely to shift or deflect. Taper also helps to gradually increase the size of the hole being drilled, which helps reduce stress on the tool and the material being drilled.
Second, the tapered design helps evacuate cuttings (swarf) produced while drilling. The taper provides a path for the chips to flow out of the hole, reducing the chance of the tool clogging or the hole becoming full of chips. This helps to extend the life of the tool and improve the overall quality of the hole drilled.
Finally, the taper also helps provide a secure fit between the tool and the chuck or collet that holds it in the drilling machine. This helps reduce the chance of the tool becoming loose during use and potentially damaging the material or machine.
Benefits of using tapered drilling tools
There are several benefits to using a tapered drilling tool, including:
Improved Accuracy: The tapered shape of the tool provides better guidance when starting to drill, reducing the possibility of the tool drifting or veering off the desired path. This can result in more accurate and precise holes.
Increased Stability: The gradual increase in diameter provided by the taper helps reduce stress on the tool and the material being drilled, resulting in a more stable drilling process. This can lead to higher quality holes and longer tool life.
Better Chip Evacuation: The taper provides a path for chips (swarf) created during drilling to flow out of the hole, reducing the likelihood of the tool clogging or the hole becoming filled with chips. This helps to extend the life of the tool and improve the overall quality of the hole drilled.
Versatility: Tapered drilling tools
can be used on a variety of materials including wood, metal, plastic and composites. They can also be used in a variety of drilling applications, from drilling small pilot holes to creating larger holes for bolts and screws.
Reduced Risk of Damage: The taper provides a secure fit between the tool and the chuck or collet that secures it in the drill, reducing the chance of the tool becoming loose during use and potentially damaging the material or machine.
Overall, tapered drilling tools
can provide greater accuracy, stability, chip evacuation, versatility, and lower risk of damage than other types of drilling tools.
