What are metal drill bits?
Metal core bits are high-tech special attachments for fast and accurate drilling of large holes even in super-hard materials. This consumable is attached to drills, machine tools and screwdrivers (impact drivers).
What materials are metal core bits suitable for:
- metal;
- steel;
- aluminium;
- copper;
- cast iron;
- stainless steel.
Some models are even suitable for wood, brick and plastic. In general, the tool is designed for drilling holes with clear edges and large diameters. When cutting out a ring, the tool leaves a whole cylinder (core) inside. Less effort – better results.
When you buy metal core bits from VADA, you get a reliable tool for any task, from professional to domestic.
Where are metal core bits used?
Buying metal core bits is a necessary requirement not only for construction and engineering work, but also for ordinary household repairs.
The main areas of application for metal core bits are:
- construction;
- electricity;
- mechanical engineering;
- plumbing;
- repairs;
- installation of ventilation and heating systems;
- manufacture of metal structures;
- furniture production;
- installation of metal structures;
- locksmith and manufacturing work.
Examples of specific tasks for which metal core bits are used:
- creating holes for cable ducts;
- installation of electrical panels and enclosures;
- fastening metal elements;
- repair of car bodies and metal parts;
- manufacture of metal enclosures and parts;
- installation of industrial equipment;
- manufacturing brackets;
- installing locks, handles, fasteners;
- creating furniture, namely metal frames for tables and chairs, racks with cabinets and pedestals;
- installing fasteners for fire detectors;
- installing alarms and other security system components.
If such attachments are in the arsenal of tools in a garage, workshop or private home, they are most likely used to repair cars, generators, metal cabinets, etc.
Main types of metal drill bits
Different categories of drill bits are suitable for specific tasks. Therefore, when buying metal drill bits, it is important to consider the material, metal thickness and type of tool.
Metal drill bits are divided into the following types:
- Bimetal metal drill bits (HSS Bi-Met) are universal consumables suitable for most metals, as well as wood and plastic.
- with carbide teeth (carbide, HM) — even better for thick or hardened metal;
- diamond coating — suitable for particularly hard alloys or composites, and for domestic use — thin metal and tiles;
- A set of metal core bits is the ideal option, as it contains core bits of various diameters, making it suitable for domestic and professional use.
The most popular and versatile type is the bimetal core bit. Replaceable core bits and core bits with a centring drill are convenient for domestic use.
How to choose the right metal core bits?
If you make the wrong choice, the equipment may burn out or break. And the drilled holes will be far from clear and even.
Before buying metal core bits, it is worth comparing models and considering the following characteristics:
- the material to be drilled;
- the thickness of the metal to be drilled;
- type of fastening (hexagonal, cylindrical, SDS-plus, etc.);
- hole diameter (20-35 mm is sufficient for household use, while 76-100 mm is recommended for large holes);
- cutting depth (standard depth is sufficient for thin sheet metal, while a deeper core bit is required for pipes or thick parts);
- whether lubrication and cooling are provided – this is critical for metal;
- type of teeth, their quality (very cheap ones can become ‘blunt’ after 2-3 uses);
A set of metal core bits is definitely a good buy. Individual bits can be much more expensive. A set includes several bits for any task. The set comes with everything you need: a holder (adapter), drill bit, and wrench (hex key).
To check whether the bit is compatible with the tool, you need to specify the shank, centring drill bit and adapter.
Tips for safe use of the bit (in domestic and professional conditions):
- cool during drilling,
- protect your eyes and hands during work;
- use low speeds for large diameters;
- do not neglect cooling and lubrication (for example, WD-40 reduces overheating);
- it is advisable to use a respirator;
- before drilling, check that there are no cables inside metal enclosures or shields;
- secure the part firmly, but not with your hand (you can use a vice or clamps);
- do not press too hard on the tool;
- check all teeth for wear.
It is important to remember that the core bit only cuts along the edge, not the entire metal inside the hole.
