ARTU 01021 Drill Bit, 3/16 in Dia, 5-1/2 in OAL, Parabolic Flute, 3/16 in Dia Shank, Straight Shank

Made of chrome vanadium steel shank for enormous strength, for use with Tapcon fasteners. Special negative back grinding enables the tip to bore through applications such as masonry, ceramic tile, concrete, brick, fiberglass, plexiglas, cast metals, hardened steel, granite, marble, woods and plastic with a filing action rather than a cutting action. Requires no center punch, eliminates walking and can be re-sharpened. NOTE: not recommended for use on mild steel, e.g. aluminum, angle iron, copper, galvanized pipe, brass and stainless steel. Conforms to ANSI standards.

Made of chrome vanadium steel with a black oxide finish, measuring 3/16 in in diameter, with applicable materials Cast Metal Ceramic Fiberglass Glass Granite Hardened Steel Hardwood Marble Masonry Plexiglas PVC Softwood, cutting edge material Carbide, flute length 3-1/4 in.

Application

For rotary or percussion drilling

• Chrome vanadium steel shank for enormous strength and flexibility
• Outlasts regular carbide-tipped bits
• Requires no center punch and eliminates walking
• Resharpens on a high-quality silicon carbide grinding wheel
• Uses standard coolants such as turpentine, light oil, water
• Flat bottom parabolic flute for faster waste removal
• Special negative back grinding enables the tip to bore through materials with a filing action, not cutting
• The blend and high tech bonding of cobalt and tungsten carbide allows bit to withstand temperatures up to 2000 deg F
