Shefcutήprecision reamers and boring tools aredesigned to produce accurately sized, extremely straight and round bores with fine surface finishes. Multiple guide pads rigidly support a single, replaceable cutting blade for exceptional stabilityand alignment. Size control, surface finish quality,and hole geometry are superior, compared to results from conventional reamers and boring tools. Each tool is designed for a specific cut diameter.Standard and custom tool designs are offered. Alsoavailable from Cogsdill: tool holders designed tocomplement and enhance the performance of Shefcut tools,...

Shefcut > ή tools are designed for precision reaming orboring operations.The manner in which the tools are appliedresults in some differences in tool design and machining set-up: > Shefcut tools are often used in precision reaming applications,where the tool is allowed to locate in the prepared bore.The Shefcut precision reamer is usually run at lower surface speeds,and is held directly in the spindle,in a floating tool holder or in a precision CNC holder.The tool body is necked downӔimmediately behind the cutting head for increased flexibility,since the tool will seek the bore until the...

Shefcut tools are also designed and built for asingle,replaceable cutting blade supported by guide pads, providing exceptional stability and alignment for superior results. precision boring applications,where the tool is used for accurate bore location.The Shefcut precision boring tool is usually run at higher spindle speeds in a rigid machining set-up,and can often be applied directly to a cast bore.The tool is held with a highly accurate spindle connection (e.g.,HSK),or in an adjustable tool holder.The precision boring tool is designed for enhanced rigidity for very accurate bore...

A few examples illustratingour special tool design capabilities and applications follow. The Shefcutή design concept is tailored to suit a wide variety of applications,including tools for multiple or step diameters,short or extended work lengths, extended pad lengths,front pilots,or special shanks,and tools for use in applications where unique machining set-up requirements exist.Cogsdill offers custom tool design and applications engineering assistance. NOTE: A completed Application Data Sheet (see page 43) should be enclosed with your request for quotation, along with your part print. >...
