• Location and depth of grooves easy to adjust.

• Simple to changes cutter from different grooves shapes.

• Changing of bushing and cutter allows one tool to cover a range of hole diameters.

• The life of cutter extendable by resharpening.

Tube Sheet Hole Radius Cutter

•High speed steel tool used in preparing tube sheets to suit the flaring or beading of tube ends outside of or flush with the tube sheet.

• MM sizes and cutters with other radii are also available

Tube End Facer

TEF Series

• Tools bits coated with Titanium Nitride to give 3 times the life of convertional tool bits.

•Ideal for quick facing of projecting tube ends in heat exchange condenser and boilers.

• One size of tool is suitable for use on multiple tube thicknesses by interchanging pilot.

• (TEF-375 is the exception with the tool suitable for one tube ID only.)

• Each tool is suplied with a set of multiple to cover all thicknesses.

• Tube and facers for MM size of tube also available.

FB Series

• High speed production tool.

• Titanium Nitride coated tool bit can be reversed and used. Double tool bit life.

FC Series

• Tool uses 3 cutting blades which can be configured for tube end facing or weld removel as a step in the removel of welded tubes from tube sheet.

• Tool fitted with MT shank for use with standard air or electric drills.

• Cutting blades are Titanium Nitride coated to give 3 times the life of conventional cutting blades.

• Tools available for MM sizes of tubes also.

• Ideally suited for work on larger diameter boiler tubes.

Flaring Tool

Beading Tool

Belling Tool

In many condensers the inlet end of tubes are required to be seated into the sheet. The contour is a "Bell End" or "Trumpet Mouth" of special shape
