Solid Carbide Coolant Through Drill increases overall throughput.

Press Release Summary:

With CTW™ (Continually Thinned Web) flute geometry that optimizes flute volume and breaks chips into small, manageable pieces, MP-X 8xD reduces machining time for operators by eliminating pecking process. Chip evacuation speed and efficacy helps reduce cost-per-hole while also increasing throughput. Promoting wear resistance and tool life, construction is of microgram carbide. Multi-layer TiAIN coating lends stability to cutting edges and provides oxidation stability.

Original Press Release:

Solid Carbide MPX Drill Reduces Cost-Per-Hole

The high performance Dormer MP-X 8xD drill provides increased productivity for operators.

Building on the reliable technology of the high performance solid carbide MP-X 3xD and 5xD drills, the new coolant through 8xD drill reduces machining time for operators by eliminating the pecking process.

With fast and efficient chip evacuation, the MP-X 8xD aligns with the comprehensive Dormer Pramet range of cutting tools by reducing the cost-per-hole and increasing overall throughput for users.

The microgram carbide material provides an excellent combination of hardness and toughness, resulting in high wear resistance and longer tool life. With multi-layer Titanium Aluminum Nitride (TiAIN-Top) coating, the Dormer MP-X drill delivers:

Improved stability to the cutting edges

Outstanding wear protection

High hardness / toughness and oxidation stability

The CTW™ (Continually Thinned Web) flute geometry optimizes flute volume and breaks the chips into small, manageable pieces to ensure efficient chip evacuation in deep hold applications, reducing machine downtime.

CTW™ ensures consistent forces throughout the drilling cycle. The combination of the split four facet point and the CTW™ flute delivers precise centering and low thrust forces.

The MP-X 8xD is a worthy addition to the comprehensive Dormer Pramet cutting tool portfolio.
