摘要： A drill for producing close tolerance holes in non-ferrous and non-metallic composite materials in which the essentially cylindrical size of the body of the drill is maintained all the way to the drilling point, the cylindrical shape as it approaches the drilling point is tapered by being flattened off on opposite sides to taper the body, and the drilling point has symmetrically formed and angularly related cutting edges in the opposite edges of the flattened and tapered body. The drill having the foregoing characteristics may be combined with a countersink formed either separately from or as an integral part of the drill.

摘要： A feed mechanism, for use with a right angle drill, capable of feeding a drill bit into a workpiece at variable thrust and position. The feed mechanism, attached to the cutting end of the drill, utilizes the mechanical advantage of a threaded member to feed the drill bit into and out of the workpiece. The entire drill and feed mechanism is held stationery during operation by a holding means which is fixedly attached to the workpiece and in which the feed mechanism is locked.

摘要： There is provided by this invention a chip extraction apparatus for extracting chip swarf from a workpiece for collection in an external vacuum source. The chip extraction apparatus is comprised of a nosepiece assembly which houses a spring/atmospheric pressure actuated piston for providing telescopic capabilities to a drill bushing. The drill bushing contains an air inlet port for allowing air to be drawn into the interior fo the drill bushing where it will mix with chip swarf. The air application assists chip flow and contributes to efficient vacuum withdrawal of chip swarf from the drill flutes into the vaccum chamber of the nosepiece assembly. The chip swarf is eventually expelled through a vacuum port in the nosepiece assembly to the external vacuum source. Alternative drill bushing configurations are disclosed to provide consistent chip extraction rates for different material requirements and cutting tool types. Additionally, a means for introducing coolant/lubricant or pressurized air to, and removing coolant/lubricant or pressurized air from, the surface of the workpiece is disclosed. The chip extraction apparatus is disclosed in the context of both a portable drill used in conjunction will drill plates and a handheld drill in which the nosepiece assembly is eliminated, but the chip extraction capability is retained.
摘要翻译： 本发明提供一种芯片提取装置，用于从外部真空源收集工件中提取切屑， 芯片提取装置由容纳弹簧/大气压致动活塞的鼻梁组件组成，用于向钻套提供伸缩能力。 钻套管包含用于允许空气被吸入钻孔套管内部的空气入口，在那里它将与切屑相混合。 空气应用有助于芯片流动，并有助于芯片切屑从钻孔槽有效地真空抽出到喷嘴组件的真空室中。 芯片切屑最终通过喷嘴组件中的真空口排出到外部真空源。 公开了替代的钻孔套管配置，以提供用于不同材料要求和切削刀具类型的一致的切屑提取速率。 另外，公开了一种用于将冷却剂/润滑剂或加压空气引入到工件表面并从工件表面除去冷却剂/润滑剂或加压空气的装置。 芯片提取装置在结合使用的便携式钻孔的情况下被公开，钻孔板和手动钻头，其中消除了喷嘴组件，但是芯片提取能力被保留。
