Kennametal 5964171 Carbide Replaceable Tip Drill Ksem

Product Description

The KENNAMETAL 5964171 is a solid carbide replaceable tip drill in the KSEM series, designed for high-performance drilling in demanding production environments. The tip carries a TiAlN (AlTiN) PVD coating applied over a fine-grain carbide substrate in grade KCMS35, delivering hardness and thermal resistance across a broad range of workpiece materials. The cutting diameter measures 0.4688 inches (11.91 mm), the functional length is 0.5000 inches, and the overall projection is 0.6700 inches. The 140-degree included angle point geometry is suited for entry and exit on challenging surface conditions. Licensed HVAC, machining, and tool-room professionals install this tip as a field-replaceable insert on compatible KSEM drill bodies.

This replaceable tip drill is applied in steel, stainless steel, non-ferrous metals, superalloys, and titanium workpieces. The SPL insert geometry with a 2-flute, 4-margin configuration supports stacked-plate drilling and inclined-exit drilling, making it appropriate for structural, aerospace, and general metalworking operations where consistent hole quality and insert changeability are priorities. It fits an insert seat size 5 KSEM drill body and accepts helical flute geometry with a regular spiral type. The flute length is 13.00 mm. This tip is installed without through-coolant, relying on external or flood coolant delivery at the machine.

Key Features

• 0.4688 inch (11.91 mm) cutting diameter with a 140-degree included drill point angle
• SPL insert geometry with 2-flute, 4-margin design for stability and hole roundness
• Rated for steel (P), stainless steel (M), non-ferrous metals (N), superalloys and titanium (S)
• Supports stacked-plate and inclined-exit drilling applications
• Clamp-style insert holding for secure seating and repeatable tip positioning

Compatibility

Designed for use with KSEM series drill bodies accepting insert seat size 5 replaceable tips. ISO number KSEM1000SPL. No specific compatible drill body model numbers were provided in the input data; consult KENNAMETAL KSEM tooling documentation to confirm body compatibility before ordering.

Installation Notes

Replaceable carbide tips of this type are installed and replaced by machinists or toolroom technicians using the clamp mechanism on the KSEM drill body; follow the tool manufacturer torque and clamping procedure documented in the KSEM assembly guide. Ensure the drill body and machine spindle are fully de-energized and locked out before removing or seating the insert tip. Inspect the insert seat for chips or debris before installation to avoid tip seating errors. This tip does not support internal coolant delivery, so confirm that external or flood coolant is adequate for the intended operation.
