Splines

Tools for Splined Profiles

The spline profile broach tool line was designed to make splined internal profiles. The choice of tool is determined by the minimum entry hole of the workpiece to be machined. In fact, we recommend purchasing a tool with a diameter (D2) as close to the value of said hole as possible. It is also possible to make special tools in various diameters and sizes based on specific customer needs.

Slots

Broaching and Slotting Inserts

The inserts designed to work exclusively with duMONT Tool Holders are a sintered steel alloy with a 13% cobalt content, heat treated to a 72 HRC hardness providing toughness and impact resistance. A TiN coating is applied to improve wear resistance and lubricity. All inserts are designed to allow several re-sharpenings.  View the Engineering Section of our catalog below for process and Special Insert information and available applications – Keyways in Tapered Bore, Square, Hexagon and Involute Internal Gears. We can add custom corner radius per your requirement.

Keyways

Stock Tool Holders for Inch and Metric Keyway and Slotting Inserts

The Tool Holders designed to work exclusively with duMONT Stock Keyway and Slotting Inserts are heat treated tool steel, hardened to 58/60 HRC at the Insert seat providing resistance to deformation and longer tool life. Most Tool Holders provide two 3.55mm holes for Thru Tool Coolant delivery promoting lubrication, cooling and chip flushing improving finish and tool performance.

Squares

Tools and Inserts for Square

Our series of duMONT tools was developed to execute internal squares. It offers the following advantages: absolute concentricity, the possibility of correcting the required measurement, machining speed and cost savings. Every insert size in this line is able to execute various square sizes, which makes using duMONT tools for squares very economical and convenient.

Hexagons

Tools and Inserts for Hexagon

The duMONT CNC Indexable Broaching System was developed to execute internal hexagons. It offers the following advantages: absolute concentricity, the possibility of correcting the required measurement, machining speed and cost savings. Every insert size in this line is able to execute various hexagonal sizes, which makes using duMONT tools for hexagons very economical and convenient.
