Tech Tip #8 - Fundamentals of Drilling

There are many factors to consider when deciding which drill is best to purchase for your applications. Make sure that: The drill is fully equipped and engineered specifically for the type of material that you’re cutting The drill is prepared for proper chip evacuation with polished chip flutes for easy evacuation The drill provides efficient internal coolant supply for drills greater than 3xD in length for proper heat management and chip evacuation

Drilling a Steel Stack with the HPX Drill for Steels

Kennametal's HPX solid carbide drill for steels features a straight cutting edge that reduces build-up and chipping on the cutting edge and margin land. The patented HPX point provides excellent self-centering capabilities, reduces thrust and enables precise center chip formation. 2 margin lands provide stability, reduce friction. Up to 3 times higher cutting parameters, saving machining time and freeing up capacity. Ultra-high polished chip flutes reduce friction, improve chip evacuation and increase tool life. A continuous chip-flute cross-section reduces vibrations and reduces cutting edge chipping. MQL-ready! All shanks fulfill the DIN 6535 and 69090-03 requirements for minimum-quantity lubrication.

Ramping With the New SGE-R Insert for Mill 4-15™

The Mill 4-15 series is specially engineered to achieve excellent surface quality and higher metal removal rates in shoulder milling applications. The unique design allows you to apply the tool in multiple passes, called “step down”. Most tools leave tool marks with every pass they take, resulting in unsatisfactory or low-quality wall finishes. This usually requires another finishing pass at the very end of the process. Not with the Mill 4-15 as it eliminates that finishing pass with an additional tool, saving time and money. The SGE-R geometry adds to the capabilities of the Mill 4-15 series, enabling ramping operations and helical interpolation.

Cutting "Swiss Cheese" With The Mill 4™-12KT

Handling even the most severely interrupted cuts with ease, the Mill 4™-12KT is a staple of stability and strength when it comes to indexable milling. Tangentially mounted inserts have shallower pockets which allow for a larger core size of the cutter, very strong cutting edges on the inserts, and easy access to insert screws. Mill 4-12KT requires up to 15% less horsepower, enabling increased feed rates, even on small machines. The patented insert design — featuring a triangular shaped margin — provides unprecedented stability in steel and cast iron applications. https://okt.to/QyNoYt

HARVI™ I TE Ball Nose Style End Mill with Rippled Relief

HARVI™ I TE Ball Nose Style End Mill with Rippled Relief

Kennametal is proud to introduce the HARVI™ I TE ball nose end mill.  Designed for highly productive 3D roughing and finishing operations, it delivers lower machining cost through maximum metal removal in a broad range of materials.  The HARVI I TE ball nose end mill features an innovative proprietary relief in the most critical area - the ball nose section - a wavy contour shapes the rippled relief which provides improved coolant flow into the cutting zone. The rippled relief enables higher feeds and speeds as well as increased depth of cuts by advanced vibration damping and lower cutting forces. On the outer diameter, the relief changes its shape, and turns into the eccentric faceted relief. The eccentric faceted relief provides exceptional edge strength, geometric accuracy, lower cutting forces and makes this end mill series very versatile.  Other geometry advancements of the square end styles —including a twisted end face, chip gashing, and a variable helix angle—have also been engineered into this new solid carbide end mill.
