Reconditioning To complement the extensive range of PHP Solid Carbide tooling offered by Precision Twist Drill, we offer you a reconditioning service for worn or damaged PHP drills. Reconditioning Reduces Costs Reconditioning can halp your overall cost per hole. Most tooling can be reconditioned up to three times, while maintaining its original high performance capabilities. Reconditioning costs are a fraction of the cost of new tools. Therefore, you can reduce your total tool costs by as much as 50% by reconditioning the recommended three times. Recoating Services To obtain high material removal rates with the same tool life, PHP drills must be recoated again after reconditioning Note: Reconditioned and recoated tools have the probability to be oversized due to the diameter tolerance and back taper, and coating thickness due to recoating. Continuous Quality All recommended tools are inspected using quality standards in Precisions ISO certified environment , ensuring reconditioned tools have the same exacting standards as original tools. Reconditioning Policy Delivery in 15 working days (quantities 30 or less) Tools are laser marked after each reconditioning Tools returned in new protective packaging Reconditioned tools can only achieve their original performance if they are sent in a moderate state of wear, without serious damage. Precision reserves the right to refuse a tool for reconditioning based on inspection.

PHP Benefits Enhanced Geometry The key to the success of drilling is to apply a geometry which will form, accommodate, and evacuate a chip, carrying away the heat. The combination of a point geometry and flute are critical. The PHP’s self-centering point reduces thrust and controls ship formation at the axis of he point. This cutting action improves dimensional accuracy, provides for a freer cutting tool action, and faster metal removal rates. The PHP flute form acts as a chip breaker so tightly curled chips are kept away from the inner-hole wall, thus improving its surface finish and reducing torque associated with chip congestion. This improved control allows for easier chip evacuation. PHP Coatings With the increased demand for faster metal removal rates, the acceptance of coated product is advancing. The most proven coatings are TiN and TiALN which creates an improved thermal barrier by providing increased wear resistance and higher oxidation threshold. The key to its success is the addition of aluminum, which increases the hot hardness capability. Increased Productivity The PHP drill can increase your productivity by a factor of 20 times over high speed steel as seen by the graph shown to the right. Plus, increased penetration rates, which reduce the cycle time for producing a hole. The result, lower cost per hole.
