Description of Hegebeck Reduced Cutting Straight Drilling Cutting Tools
MATERIAL-This reduced shank drill Bit was made by High Speed Steel which is good for most general purpose applications, featuring a combination of hardness and toughness for wear resistance. ADVANTAGE-Design of reduced shank can expanding the size range capacity of a portable drill chuck; Common flute and overall length for minimal adjustment during tool changes. FEATURE-Black oxide treatment adds lubricity. Small pockets on the surface of the tool that act to hold coolant near the cutting edge. APPLICATIONS-Designed for fast drilling in concrete, masonry, artificial stone, and rockDesign for drilling in low and medium tensile strength materials, such aluminum, iron, copper, brass and metal. PlEASE NOTE - To make clean and precise holes, water is required for lubrication and cooling when drilling metals. Increased use of water lubrication will extend drill bit life.
