|Criterion's Qualified Length Tools and Qualified Length Adapters|
06 December 2012
One of our main objectives is to provide products and solutions for our customers that will save them money and reduce their cost of manufacturing. Shortly after introducing the 1/8" solid carbide tools we introduced the “QL” boring tool to our line of solid carbide boring tools.
These .125" diameter solid carbide qualified length boring tools feature a repeatable “Z” length of +.001" /-.001" from a nominal set length. The QL tool’s close tolerance length minimizes a machine’s down time when you have to change a tool during production run.
When a tool needs to be replaced you loosen the collet nut remove the damaged tool, insert the replacement tool, rotate it until it falls into place. The tools closely held locating angle insure the “Z” length repeatability. The locating angle also places the cutting edge on center giving longer tool life and reducing machine down time.
There are 17 different bore diameter and length configurations of the new .125" solid carbide qualified length boring tools. Minimum bore diameters will range from as small as .050" to as large as .110" in diameter. The boring tools are able to bore holes up to .700" in depth depending on the bore diameter.
The qualified length tools need to be held in a Criterion qualified length tool holder. The tool holders are available with 1/4", 3/8", 1/2", 5/8" and 3/4" shanks and are design for use in Criterion’s precision boring heads.
