Speedy Handle Tool

From Severance Tool Industries Inc. comes the Speedy Handle tool for use with Midget Mills, rotary files, deburring and chamfering cutters, countersinks, and a wide variety of other bits used in detailed finishing work. The convenience and quick setup of Speedy Handle make it a suitable alternative to air- or electric-driven power tools in applications involving one or two holes or light forming operations.

The screwdriver-like handle design features a knurled surface texture for easy gripping. Plus an integral quick hold and release mechanism that makes tool changes fast. An ergonomic ratchet-type twisting action keeps the hand on the handle to minimize fatigue and tools on the work surface for uninterrupted, smooth cutting action.

The Speedy Handle accepts all ¼" shank diameter rotary finishing tools. The handle is available as a single unit or in a prepacked set with three Severance tools: a ball-shaped Midget Mill tool, an inside chamfering mill and a four-flute Chatterless countersink.

Machining a bevel on a workpiece or tool; improves a tool's entrance into the cut.

Tool that cuts a sloped depression at the top of a hole to permit a screw head or other object to rest flush with the surface of the workpiece.

Phenomenon leading to fracture under repeated or fluctuating stresses having a maximum value less than the tensile strength of the material. Fatigue fractures are progressive, beginning as minute cracks that grow under the action of the fluctuating stress.

Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.

Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.

Repetitive or random deviations from the nominal surface, which form 3-D topography of the surface. See flows; lay; roughness; waviness.
