Handling a Wide Range of Materials
The Docchimo Two-sided Hole Saw is ideal for boring hoes up to 4.5 mm long in stainless steel plates, steel plates, aluminum plates, PVC sheets, fiber reinforced plastic, enamel, stainless steel pipe, steel pipe and cast iron pipe as well as up to 15 mm long in ceramic siding, metal siding laminated boards and artificial marble.

Features:

• The two-sided drill bit is from 21 to 55 mm, greatly decreasing bit costs by cutting twice as much material with one bit.
• The bit can be easily replaced and the snap-in shank removes chips easily. A single shank handles all sizes of bits from 14 to 20 mm.

Adaptable Power Drill Bits
For power drills with chucks 10 mm or greater, vibrating drills and lightweight SDS hammer drills always use a rotating type drill bit.

Handling a Range of Materials
In the past, you had to select the core drill bit to match the material you were drilling, but with House BM’s new multipurpose bit, those days are over. Some of the many materials that can be drilled include the following:

Power drill vibration mode, chuck capacity: 13 mm
Mortar, concrete blocks, brick

Power drill rotation mode, chuck capacity: 13 mm
Ceramic and metal siding, autoclaved lightweight           aerated concrete, galvanized plates, colored           galvanized iron plates, wood and plywood,           bonded wood, slate, wood cement board, PVC           sheets and pipes

Wide Tip & Center Drill with easy cutting scrap removal
Multiple wide tips are provided at the end of the           tool. When drilling, a gap is formed between the           blade tip and the material to allow easy removal           of cutting scraps with the easy scrap removal           function.

Note that House BM’s multipurpose bits cannot drill concrete with reinforcing bar.
