Solid Carbide 2 & 3 Flute High Performance Drills

MEL-EX3

Highly effective in a wide variety of materials, our 2 & 3 flute High Performance Drills can be used for either drilling from solid or upsizing a pre-existing or cast hole.

Our “Select-a-Size” program allows you to choose a drill diameter size specifically suited to your drilling application. Mohawk's unique standard tooling concept allows you to select what other companies would consider special... without compromising on price and delivery. Upon agreement, we will even stock specific sizes, for same day delivery.

Choose from two overall lengths within each diameter range and specify your coating of choice.

Features

MAXIMUM STRENGTH
Heavier web (core diameter) throughout the drill body increases rigidity providing longer tool life.

POINT STYLE
Our special point style with 140° angle provides dynamic features adapted to reduce thrust, while providing easier penetration, superior self-centering capabilities as well as better tool life and size control.

CARBIDE GRADE
We use ultra-fine carbide grade specifically suitable for High Performance Drilling operations.
This grade provides better cutting edge strength, resists chipping and has excellent wear prevention characteristics. Further increase tool life within a selection of coatings.

FLUTE FORMATION
Unique flute geometry generates a profile that produces short curled chips that are more easily evacuated from the holes being drilled. Such elements facilitate higher penetration rates, improved surface finish and generally improved all around cutting condition.

MEL-EX3

The MEL-EX3 is a high precision three-flute drill capable of performing first-class drill-reaming in one pass. Where standard carbide tools typically require super-rigid set-ups, the MEL-EX3’s sturdy design permits use on a broader range of machines which may not require such strict and uniform feed requirements.


These 3-flute drills are highly effective in a wide variety of materials for either drilling from solid or upsizing a pre-existing or cast hole. Available in a size to suit your requirements.





Features

CARBIDE GRADE
Mohawk uses ultra-fine carbide grade for all its high performance drills. This grade gives improved cutting edge strength and stability, preventing premature chipping and material loading. Its ultra-fine grain size allows us to give sharper cutting edges, leading to more consistent hole-making operations.

THREE CUTTING EDGES
The MEL-EX3’s three-flute construction distributes the cutting forces to 3 cutting edges instead of 2. In addition, the extra flute enables the MEL-EX3 to track straighter while in the hole, vastly reducing runout. The third land produces a burnished-quality surface finish, thereby eliminating the need to ream separately when hole tolerance and surface finish permits. The MEL-EX3 design also allows the drill to start or end on uneven surfaces and to handle interrupted cuts without deflection.


Point Style A (PN10-65A)
Extensive web thinning produces an aggressive, naturally self-centering “universal” point, eliminating the need for spotting and reducing the drill’s tendency to wander. The 130° point angle aids in accommodating the third flute and contributes to the production of narrower chips.


Point Style C (PN10-65C)
Sharing many of the benefits of the A point, the C point sports a spiral design which provides top performance when machining gray cast iron, spheroidal graphite iron, malleable cast iron, aluminum alloys, magnesium alloys, brass, steel and cast steel.
