2-holes bars solutions for tool bodies

Forécreu hole bars are the ultimate solution for the manufacture of tool bodies. Durable and available in several grades, they are suitable for all tooling projects in the machining sector. Trust our over 70 years of expertise to design reliable tool bodies that last over time.

Forécreu’s range of hole bars for tool bodies is compatible with all tool bodies: insert tool bodies, carbide-head tool bodies…

Tool bodies are subjected to different stresses during use. The materials used for tool body hole bars must meet the following requirements: machinability, grindability and toughness. For this purpose, Forécreu uses special steels known for their exceptional hardness, wear resistance, resistance to thermal fatigue, high-speed operation, etc. This type of material reduces grinding costs and improves tool body life.

Control tests are regularly carried out in our laboratory to perfect our hole-bar solutions for tool bodies (tensile tests and metallurgical tests). Quality and geometry checks are also carried out throughout the manufacturing chain.

Hole bars for carbide-head tool bodies

Our oil-hole bars for carbide-head tool bodies are supplied with straight or twisted holes to meet your specifications. They are available in 3 geometries to suit all types of tool bodies, i.e. 3 positions and diameters of holes in the bar.

Standard geometry: optimized hole diameter and spacing for the most common tools
Geometry reduced to 80% of standard dimensions: slightly reduced hole diameter and spacing for slight oversize shanks (e.g. DIN 6535 standard shanks).
Geometry reduced to 65% of standard dimensions: drastically reduced hole diameters and center distances to enable the production of one-piece tool bodies.

Unless you specify otherwise, bars are supplied in standard lengths from 1.8 to 3.9 meters. Our metallurgists are at your disposal to assist you in your search for hole bars for tool bodies. Take advantage of their advice and expertise to choose the hole bar best suited to your machining project.
