Bell-hanger drill bits are long bits that make holes through walls, studs, flooring, and other surfaces so wires can be pulled through these surfaces for hooking up televisions, telephones, alarm systems, computer networks, and other equipment. They are also known as installer bits, feeler bits, and fishing bits because they have a hole near their tip for threading wire onto the bits to pull it through the surfaces after drilling.

Self-feed drill bits have beveled saw teeth and a screw tip that pulls the bits into the workpiece to quickly bore holes in wood without applying pressure. The bits' teeth can be resharpened and their screw tip can be replaced to extend the bits' life. These bits feature a quick-change hex shank and can be inserted and removed from the drill chuck without the use of tools, allowing the bits to be changed out faster and more efficiently than bits with a standard hex shank.

Chamfer profile router bits create a 45° angled edge on a workpiece. They are also known as bevel-tip profile router bits.

These components are used to replace the blades on compatible self-feed drill bits that use replaceable blades to form the bits' cutting edges. The replacement blades save users the downtime required for re-sharpening the bits' cutting edges.

Drill bit countersinks can drill and countersink a hole in one step for maximum productivity. They produce a chamfered hole with a tapered opening that allows screws to install flush with the surface of the workpiece for a finished look. These sets contain multiple drill bit countersinks in a range of sizes.

The SHOCKWAVE Lineman's Impact Auger Bits are engineered to deliver cleaner, faster holes in wooden utility poles. They feature a single spur design, which scores the edge of the hole, creating a cleaner finish that allows bolts to slide through without resistance. The bits are coated with a reinforced anti-friction PTFE coating for overall smoother drilling and easier removal of the bit from the pole. The aggressive feed screw and cutting edge pull the bit through the material while the optimized wide flute geometry quickly ejects the chips to clear the hole and reduce clogs, leading to overall faster drilling speeds.

The MILWAUKEE RED HELIX Cobalt 23 Piece Drill Bit Set is engineered for extreme durability and longer life in hard metal applications. The Milwaukee Cobalt drill bits are designed with a VARIABLE HELIX that includes an aggressive 35° Helix Angle which ends at 15°. The drill bits have QUADEDGE TIP to decrease heat buildup and drill faster. The 135° split point tip delivers a precision start and prevents walking for fast, accurate holes in Hard Metal, PVC and wood.The tapered drill bits feature a new ENHANCED TAPERED WEB that strengthens the bit's core to increase flute durability. The cobalt twist drill bits are ideal for tough applications, providing up to 15X life vs. Black Oxide Drill Bits. This set includes 23 bits from 1/16" to 1/2".

These sets include multiple self-feed drill bits of various sizes for creating holes of different sizes. The bits have beveled saw teeth and a screw tip that pulls the bits into the workpiece to quickly bore holes in wood without applying pressure.

The high-speed steel jobber-length drill bits in these sets provide more flexibility and absorb more shock and vibration than cobalt and carbide jobber-length drill bits, making them suitable for use in manual drilling machines and handheld power tools. They may leave a rough finish on the hole. These sets contain multiple drill bits of various sizes.

These sets include multiple self-feed drill bits of various sizes for creating holes of different sizes. The bits have beveled saw teeth and a screw tip that pulls the bits into the workpiece to quickly bore holes in wood without applying pressure.

This abrasive cutoff wheel features aluminum oxide abrasive material. It is suitable for cutting and grinding ferrous metal and stainless steel.

Step drill bit sets contain multiple bits in different sizes for creating holes in a range of sizes. These cone-shaped bits have steps of increasing diameter marked along their cutting head. As each bit is pushed into a piece of sheet metal or other thin material, each step on the bit widens the hole. The bits also have a self-starting split point that prevents the bits from moving, or walking, when starting to drill, which eliminates the need for using a center drill to create a starter hole before drilling.

The Milwaukee 3/4" x 72" Cable Bit is ideal for installing small wire systems in unreachable spaces. Milwaukee Cable Bits have an extra long, flexible steel shaft that lets you reach behind the wall with greater precision and ease when installing all types of small wire systems, including computer, security, phone, and cable. The bits feature holes in both ends to pull the wire through after drilling. Use the Milwaukee Placement Guide (48-08-0275) to properly locate the hole within the interior of the wall. Milwaukee Cable Bits are available in 54" and 72" lengths.
