Extra-Length HSS Drill Bit

The Drill America DWDDL8X7/64 is a 7/64-inch high-speed steel twist bit with an 8-inch overall length for deep-hole access. Its 118-degree conventional point handles general-purpose drilling across a broad range of ferrous and non-ferrous materials. The round shank fits standard chucks and tool-holding systems for production, maintenance or portable use.

Best for deep reach in mixed materials

Machinists and maintenance technicians who need extended reach in aluminium, brass, copper, steel, plastic or wood will appreciate the extra length. Users who require split-point geometry for self-centring, cobalt alloy for high-heat alloys, or a reduced shank for smaller chucks should consider other options.

118-degree conventional point

This point angle determines how the bit engages the workpiece and suits general-purpose drilling in the listed materials. It is not a self-centring split point, so starters or centre drills may be needed for precision holes. The high-speed steel construction balances wear resistance and toughness for the stated applications.

Questions about this item

What does the 118 degree point mean for drilling?

The 118 degree conventional point is a standard geometry that centres the bit quickly and works well across a wide range of materials including steel, aluminium, brass, copper, plastic and wood.

What shank type does this bit use and what chucks accept it?

It has a round shank that fits standard three-jaw drill chucks and most common tool-holding systems.

What overall length does the 8 inch dimension give you in practice?

The eight inch overall length provides extra reach for deep holes or work in confined spaces where a standard length bit cannot reach.
