Walter has extended its range of pilot drills with addition of the X·treme Pilot 180.
Deep holes nearly always require a pilot or start hole, and this is where the Walter Titex X·treme Pilot 180 comes" It's a versatile, high-performance solid carbide drill for drilling depths from approximately 2 x D. The solid carbide drill has internal cooling, which can be either emulsion or oil, and can be used with coolant pressures as low as 145 PSI. It possesses a point angle of 180 degrees, and is available in diameters from 1⁄8 – 7/8" (3 – 20mm). The drill features corner protection chamfer for maximum reliability, four margins for optimum alignment, and a TFT coating for superior protection against wear.
The new Walter Titex X·treme Pilot 180 can be used for cross holes, spot-facing inclined or convex surfaces, and for counterboring drilled holes to recess bolt heads or protect threads. Even in conditions that are not level the X·treme Pilot 180 yields precise and flat hole bottoms. It can be employed on all commonly used material groups. Application areas include general metalworking, mold and die making, and the automotive and energy industries.
Related Glossary Terms
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
Enlarging one end of a drilled hole. The enlarged hole, which is concentric with the original hole, is flat on the bottom. Counterboring is used primarily to set bolt heads and nuts below the workpiece surface.
Suspension of one liquid in another, such as oil in water.
- flat ( screw flat)
flat ( screw flat)
Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
- point angle
Included angle at the point of a twist drill or similar tool; for general-purpose tools, the point angle is typically 118°.
