Indexable Insert Drills For More Aggressive Cutting

The company’s perfoMAX indexable drills are said to enable users to increase productivity and reduce cost by boosting speeds and feeds while avoiding common problems, such as deflection, poor tool life and quality. The drill bodies have been designed for maximum stability to permit high feeds and speeds even at entry, and to resist deflection in the most challenging of applications, according to the company. Features include a large cross-sectional design with added material at the periphery to resist bending under cutting forces, an improved insert-pocket design and inserts with 90-degree corners.

The company’s perfoMAX indexable drills are said to enable users to increase productivity and reduce cost by boosting speeds and feeds while avoiding common problems, such as deflection, poor tool life and quality.

The drill bodies have been designed for maximum stability to permit high feeds and speeds even at entry, and to resist deflection in the most challenging of applications, according to the company. Features include a large cross-sectional design with added material at the periphery to resist bending under cutting forces, an improved insert-pocket design and inserts with 90-degree corners. Two coolant holes and large chip flutes with an improved flute angle and relieved front end are said to help promote efficient coolant flow and coolant and chip removal. This reduces heat buildup, prolongs tool life and produces consistent surface finishes, the company says. 

The drill bodies also feature a wear-resistant metallurgical treatment with a low-friction Teflon sintered coating, according to the company.

These drills cover a range from 0.594" to 2.375" in diameter and drilling depth capabilities from 2XD to 5XD. The drills are available with a choice of several shank styles. Included in the stationary line is a universal shank with four flats that add versatility for many lathe applications.

These drills are said to enable users to increase the productivity of many drilling operations, even difficult applications such as those with long overhang, workpieces with poor fixturing and thin-walled parts.
