Kennametal Introduces Flat Bottom Geometry for KenTIP FS
The newest addition to Kennametal’s modular drill tip series, the KenTip FS FEG insert is designed to eliminate the need for drilling and end milling flat-bottom holes, instead completing the part in a single operation.
Kennametal has expanded its replaceable drill offering for its KenTip FS modular drill series with a new FEG insert for flat-bottom hole applications. This insert is designed to eliminate the need for drilling and end milling flat-bottom holes, instead completing the part in a single operation.
The FEG insert’s geometry design features a 180-degree cutting edge and a conical center point, which acts as a pilot to provide hole position and straightness. Corner chamfers protect the cutting edges and reduce exit burrs. Four margin lands provide stability when breaking into interrupted cuts and cross-holes. The company's KCP15A grade uses a nano-structured AlTiN coating and fine-grain carbide substrate, providing toughness and wear resistance when drilling steel, stainless steel and cast iron. The diameter range covers 6.0 to 26.0 mm (0.236" to 1.024"). A drilling depth ranging to 12 times the diameter is possible depending on the KenTIP FS modular drill body.
The right choices in tooling and technique can optimize the thread turning process.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
