Top 10 Best 3/4 Inch Drill Bit

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 drilling in low and medium tensile strength materials.

A fast speedbor spade bit that features a Tri-Flute design with a fast chip ejection. Cutting spurs have 3 cutting edges. Grooved hex shank prevents slipping. Fits all standard 14-inch quick change chucks. Full screw tip allows the bit to self feed.

Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools performance is similar to uncoated tools. 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. Manufactured to National Aerospace standard 907.

QUALITY The step drill bits are made of classic high-speed steel with titanium coating for proven capability and durability in drilling holes in plastic, aluminum, copper, stainless steel and many other types of sheet metal.. 135 SPLIT POINT TIP The design of the tip angle increases cutting speed with self-centering and prevents walking off the surface of workpiece..
