LOGIQ3CHAM is a family of assembled drills carrying exchangeable carbide heads with three effective teeth. This family was designed by utilizing highly advanced technologies, based on ISCAR’s successful SUMOCHAM drills. Applying LOGIQ3CHAM drills ensures increasing productivity by up to 50% when compared with a common two-flute drill with exchangeable heads.

Features:

• General duty cutting geometry that provides effective cutting various engineering materials.
• Concave cutting edges enable smooth penetration into material, excellent centering, and stable drilling process.
• Extremely robust and precise chisel edge to withstand high loading during cutting.
• Corner chamfering to increase wear resistance and strengthen the outer corners.
• Dovetail clamping principle that prevents a head from being extracted from a drill pocket during retraction.
• A durable drill body, which carries a carbide head, is made from a hard high-strength steel grade for better wear resistance.
• The body has three polished flute surfaces to ensure smooth and easy chip evacuation.
• Variable flute angle design results in a durable body structure to sustain high axial forces.
• Internal coolant channels supply efficient cooling and lubrication during the drilling process.
• Available in several drilling depth to diameter ratios (1.5, 3 etc.).

LOGIQ3CHAM is an advanced three-flute indexable drill featuring a unique pocket design for minimal runout and a high level of repeatability. The drilling head’s a self-centering sharp point geometry ensures a reliable drilling process even when subjected to interrupted cuts and tough conditions. Cutting forces are equally divided across the drilling head’s 3 cutting edges, which can increase productivity by up to 50% compared to a conventional 2 cutting edged design.

The combination of the self-centering geometry, along with a robust and accurate clamping system results in LOGIQ3CHAM providing ultimate performances relating to hole cylindricity, roundness and enhanced productivity.

The entire machining process becomes much easier as the cutting forces are spread across 3 cutting edges, the drilling process is more stable and the penetration into the part’s material is more balanced. Thus, users can work up to twice as fast, as the feed per tooth can be increased significantly. Alternatively, users can maintain the same feed per revolution as with a two flute drill and achieve much longer tool life.

The LOGIQ3CHAM clamping, which relies on 3 points of positioning, provides high levels of repeatability when replacing the drilling head. Three radial and 3 axial stoppers secure the drilling head and ensure a reliable drilling process in high feed machining environments. Furthermore, due to its sharp edges and the low axial force it applies, the LOGIQ3CHAM is very efficient when drilling a through-hole when the drill breaks through a slanted surface, also creating fewer burrs on the hole exit. Since the material work hardening is low, a reamer or a tap which may be used for a subsequent operation will gain from extended tool life and accomplish improved results.

The unique geometry of the LOGIQ3CHAM self-centering head shapes the produced chips optimally to allow smooth evacuation throughout the 3 high helix polished flutes.

Available in Diameter Range of 12-25.9 mm with 3 & 5xD body overhang.
Exchangeable 3 Flute Drilling Heads for Carbon and Alloy Steel (ISO P) and Cast Iron (ISO K).
