20-piece HSS drill bit set

The DeWalt DW1177 is a 20-piece drill bit set manufactured from High Speed Steel with a black oxide and gold finish. It is designed for drilling into metal, wood and plastic. Each bit features a 135-degree split point tip intended to reduce walking when starting a hole.

Suited for general workshop and site use

This set suits tradespeople and DIY users who need a broad range of twist bits for mixed-material work in a single case. The 3-flat shank design helps prevent spin-out in standard three-jaw chucks. Buyers who require specialised masonry, glass or large-diameter bits should look at other options.

3-flat shank prevents chuck spin-out

The 3-flat shank on each bit engages securely with a standard drill chuck to minimise slippage under load. Size markings on the shank allow quick identification of the 20 included diameters. A tapered web adds strength to resist breakage during heavy use.

Questions about this item

What type of drill chuck is required to use the 3-Flat shank on the DW1177 bits?

The 3-Flat shank is designed to fit standard three-jaw drill chucks and helps reduce spin-out during use.

Can the DW1177 set handle the same materials as older high-speed steel bits I already own?

Yes, these bits are made from High Speed Steel and are recommended for metal, wood, and plastic, matching the range of traditional HSS bits.

How can I confirm the 135-degree split point is working properly after I start drilling?

The split point should start cutting immediately without the bit walking across the surface, giving a clean entry hole in metal, wood, or plastic.
