Kennametal Combination Tools Illinois

Kennametal Combination Tools Primary Application – Combines centering, drilling, and countersinking into a single operation, increasing productivity by reducing cycle time and number of tool changes. The modular design provides flexibility to adapt the tool to varying hole geometries in small and medium lot size manufacturing. With its slim design and full through coolant capabilities, the BF Combination System can be used even for deeper holes, critical materials, and with restricted workspace.

Features and Benefits

Modular Design

  • Adjust the drill length for different hole geometries.
  • Exchange the inserts to manufacture different countersink geometries.
  • Use through coolant Solid Carbide Drills or KenTIP Drill bodies.

HPG ‘ Drill Point Design

  • Low thrust prevents workpiece flexing.
  • Excellent centering capabilities.

KenTIP Blade

  • Easy to change right inside the machine or holder.
  • Better hole surface quality.

KC7315 Grade

  • A multilayer, TiAIN-based coating with high-hot hardness enables 100% higher cutting speeds.
  • Optimized tool surface finish ensures chip evacuation in high-speed drilling and MQL applications.

BF Inserts

  • Available standard inserts with various angles, spot-face options, and blanks.

Customization

  • Length variations available as custom solutions.
  • TX Drills for aluminum are available as custom solutions.
  • BF inserts can be customized to almost any required geometry.

SEFAS Combination Drilling System

Primary Application

Combines centering, drilling, and chamfering into a single operation, increasing productivity due by reducing cycle time number of tool changes. These productivity gains can be achieved by still using standard Solid Carbide or KenTIP The system provides full through coolant capabilities.

Features and Benefits

Using Standard SE_HP and TX Drills

  • Any style of standard HP Drill can be used achieving highest metal removal rate.
  • TX Drill combines excellent hole quality and tool life in nonferrous materials.

Using Standard KenTIP Bodies

Easy to change right inside the machine or holder.

No reconditioning required, reducing the number of tools in inventory.

Three Standard Shank Styles

  • Monoblock HSK Shank for metric drills combines high-performance drilling with the popular HSK Srank. Reduces run-out, overall tool length, and cost of an additional adapter.
  • Cylindrical shank recommended for use with Kennametal Hydraulic Chucks for increased accuracy and tool life due to a very low run-out.
  • Whistle Notch shank.

SEFAS Inserts

  • Standard inserts available with various angles and grades for use in most workpiece materials.

Customization

  • Length variations available as custom solutions.

SEFAS Combination System Options

The SEFAS combination drilling system may be used in most workpiece materials. The design and flexibility of the system can be used with a wide variety of solid carbide drills. See pages A2-Al29 for drill information.

Three types of SEFAS chamfering tools are offered: (a) integral bodies, with a compact design that provides additional workpiece and workholding clearance; (b) chamfering rings that may be mounted to Kennametal hydraulic chucks for optimal drill performance and increased productivity; and (c) high-performance HSK bodies for new machine spindles and high output applications.
