Tools: the Greycore Flexible Drill Bit is a wire-fishing drill bit designed to reach through walls and simplify cable pulls. Electricians and keen DIYers cut time and frustration when working in tight cavities. Does the 9/16 inch by 18 inch length, one-piece steel build and flexible shank make it a must-have for tradespeople?
⚡ At a Glance
- • Drilling and reach: 18 inch flexible auger reaches through wall cavities and floor voids, suitable for timber construction
- • Best for: Electricians, installers and DIYers pulling cables through stud walls and floor voids
- • Not ideal for: Masonry or metal conduit drilling where specialised bits are required
Flexible 9/16 inch by 18 inch auger pairs with an auger head to clear paths for wires. One-piece steel construction with a machine-sharpened point improves durability and retrieval.
Effortless wire pulls, thanks to fish eye holes and auger head
Fish eye holes on both ends allow attachment of cable for pulling from either direction while the auger head removes wood to create a clear channel. Machine-sharpened cutting edges and a pointed tip help start and advance the bit cleanly.
Faster, less fiddly cable runs across long or awkward routes, with fewer re-drills and less time lost on fishing.
Secure chuck grip, with a 3/16 inch flat shank
A 3-flat shank profile reduces rotation and slipping inside standard three-point drill chucks, transferring torque more reliably during heavy pushes. Compatibility covers common corded and cordless drill types with three-jaw chucks.
More consistent drilling and safer operation when forcing the bit through dense plywood or hardwood studs.
Manoeuvrability in tight spaces, with a flexible shank and tapered head
Flexible shank design allows the tool to bend around studs and obstacles, while the tapered head eases retrieval by preventing hang-ups inside the drilled void. The overall length helps reach past insulation and internal obstructions.
Access to hidden cavities without opening large access panels, making installations neater and quicker.
