Wolfcraft 40 mm Wall Breakthrough Drill Bit, 130° Tip, Hex Shank
Product description
With a 40 mm cutting diameter, this Wolfcraft wall breakthrough drill bit is intended for drilling hard brick walls. Its 130° tip is described as helping with pilot drilling and progress through the material. Need to clear drilling dust as you work? The spiral flute is designed to help remove it. The supplied details include a discrepancy about the bit’s material, so check that point before choosing it.
Who it’s for
This bit is aimed at DIYers or tradespeople who need to make a breakthrough hole in hard brick and want features directed at that task: a tip intended to ease pilot drilling, spiral geometry for dust removal and a hex shank for quicker tool changes. The stated 40 mm cutting diameter is central to the buying decision, match it to the hole required rather than relying on the general description of the bit.
It is described as impact- and shock-resistant, and as suitable for hard materials. However, the product description specifically highlights hard brick walls, so the available information does not establish how it performs in other materials. If the job is in a different material, choose a bit whose stated application covers it. A solid pick if the required hole is 40 mm and the work involves hard brick, the details do not confirm suitability for every wall type.
Technical details
- Type: Wall breakthrough drill bit
- Cutting diameter: 40 mm
- Tip angle: 130°
- Shank: Hex
- Flute: Spiral
- Point style: Brad point
- Dimensions: 16 x 45 x 525 mm
- Standard: DIN 5468
- Material: The specification table lists alloy steel, the product description calls it tungsten-carbide tipped and refers to a precision-ground hard metal plate.
That difference in the material wording is worth resolving if the tip construction is important to your choice. The description also says the bit is available in different sizes, but the details here identify this variant as 40 mm. The listed dimensions are given as supplied and are separate from the cutting diameter.
Where it shines
The design focuses on making a demanding brick-drilling task more manageable. A 130° tip is said to make pilot drilling easier, while the special spiral geometry is intended to carry drill dust away. Those features may matter when a clean, steady drilling process is more useful than choosing a general-purpose bit with no stated focus on breakthrough holes in hard brick.
The hex shank is another practical detail: the description says it enables quick tool changes. That can suit a job where swapping bits is part of the work, though no specific drill compatibility or tool requirements are provided. This is a task-specific choice rather than an all-purpose bit, for work outside hard brick, a product with that material explicitly listed would be a clearer match.
What to clarify
What material is the bit made from? The specification table says alloy steel, while the product description says it is tungsten-carbide tipped and has a hard metal plate. The supplied information does not explain how those descriptions relate, so clarify the construction if it affects your purchase.
Is this the 40 mm version? Yes, the details give a 40 mm cutting diameter. The description mentions other sizes, but does not identify them here.
What is the stated use? The product description says it is specially suited to drilling into hard brick walls. It does not confirm applications for other materials.
Final verdict
Choose this Wolfcraft bit when the job calls for a 40 mm breakthrough hole in hard brick and the 130° tip, spiral flute and hex shank suit your setup. Its stated features are relevant to that specific task, but the material descriptions do not fully agree and the available details do not establish broader material suitability. If either point is critical, clarify it before buying rather than treating this as a general-purpose drill bit.
