drills introduction hands of operators to get immediate feedback on ergonomic and performance criteria dotco and cleco drills are used daily in applications ranging from aerospace to oil fields and refineries drills in this section range from 0.3 ­ 1.0hp plus dead handles are available for several models ® ® parts interchangeability maintenance of tools can be time consuming and expensive that is why our products have been designed with high parts interchangeability with fewer parts required to repair our tools less inventory of parts is required and tools are easier to repair the handles of the new 14 series are more oval for example because that s what fits the human hand better and ensures less slippage our human engineering research also led to the addition of a new rubber grip for better temperature control because compressed air exhaust in a metal housing makes the tool cold to the hand and reduces speed and efficiency moreover the ideal is to have the line of action straight down the barrel so that the operator is pushing forward on the tool with the greatest control the greatest in-line force the least angular force and the least fatigue to the wrist that s why we designed the new drills with ergonomically-critical finger and thumb guides that s also why we added a finger lip under the trigger which keeps the other fingers from interfering with the trigger action the trigger by the way is practically forceless it requires only 4 ounces of pressure to engage the trigger and the trigger mechanism is designed with a pressurized tipvalve so that once you overcome the initial resistance you re off to the races precision parts it s simple precision parts let operators manufacture precision products whether it is a spindle a chuck a motor or an angle head our parts are manufactured from the finest materials available and are machined to the highest tolerances it is understandable why we are proud of the .0005 runout on our collet model tools the miracle of technology and human engineering technology has allowed us to make these extraordinary improvements rapid prototypes are now available through our proprietary design-engineering platform so we can do modeling in real time and put prototypes in the extraordinary new drills inspired by an extraordinary device the human hand the familiar gray dotco drill has long been the industry workhorse for the high-volume high-repetition highprecision demands of today s assembly line the new dotco drills have been dramatically redesigned ergonomically to deliver increased comfort and productivity while assuring decreased operator fatigue potential for injury and downtime on the line and we not only changed the way dotco drills look we also changed the way they perform design features double ball bearings for the spindle pre-loaded for longer bearing life and more accurate spindle control vibration and runout are reduced time-proven motor and gear design is well balanced to reduce vibration and extend tool life full feathering is accomplished with our pressurized tip-valve design for speed control while drilling each tool is individually checked aligned and adjusted on our assembly line for minimum chuck runout vibration is minimized housing is made of durable lightweight industrial grade aluminum gears are machined from alloy steel and heat-treated with fixed cages to control centers for smooth operation ergonomically critical finger and thumb guides fit the hand and aid in control the trigger is practically forceless requiring only 4 ounces of pressure to engage finger lip under the trigger keeps other fingers from interfering with the trigger action rubber grip acts as a thermal protector and isolates vibration for improved operator comfort the handles of the new 14 series are more oval because that s what fits the human hand better they are flat where they need to be flat and round where they need to be round ensuring less slippage handles are shaped to fit the human hand they are flat where they need to be flat and round where they need to be round minimal noise levels enhance operator comfort 16 warning face eye protection must be worn while operating power tools per ansi b186.1 cutting tool maximum speed rating must equal or exceed speed of air tool 90psi 620 kpa follow cutting tool manufacturer s mounting operating instructions tools must be equipped with lock-off lever to be ce compliant warning face eye protection must be worn while operating power tools per ansi b186.1 cutting tool maximum speed rating must equal or exceed speed of air tool 90psi 620 kpa follow cutting tool manufacturer s mounting operating instructions tools must be equipped with lock-off lever to be ce compliant 17
