Description of Drill America Qualtech High Speed Conventional Cutting Tools - Industrial Drill Bits
High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. Ideal for production, maintenance or portable drilling jobs.
In my experience the Industrial and Scientific drilling efficiency of these cutting tools is incredible! They work great for metals and plastics alike, cutting smoothly and accurately. The only downside is that they may be a bit pricier than other options on the market, but the quality of the results makes up for it. Overall, highly recommended for anyone needing precision drilling in an industrial setting. .
