Specification

The solution for increasing wall thickness by displacing the raw material. The increased wall thickness enables the creation of threads with high pull-out forces and high overtorque in sheets of steel, stainless steel, copper, aluminium, bronze etc. starting at a thickness of 0.5 mm. Alternative to rivet and weld nuts.

Process improvement

Time savings of up to 66 % through automation

Cost savings

No rivet or weld nuts required

Fewer process steps required

Reduced setup time

Reduces manual setup time by 50 %.

No post-processing required

0 % missed holes/threads or rotating threads

Benefits

Chipless drilling and thread cutting

No waste and disposal costs

No additional investment or storage costs

Reduction in work steps

No extraneous material necessary

High level of process reliability

Solid carbide tools offer a particularly long service life

Thread length is multiple times the original material thickness

Notice

A lubricating paste must be applied to the drill bit every 2nd or 3rd hole in order to increase its service life. Recommendations: HSP 1400 high-temperature lubricating paste.

Using a collet chuck with cooling fins is strongly recommended, as a very high heat is generated during the drilling process (700-800°C), and the collet chuck with cooling fins will significantly reduce the heat transfer to the machine spindle. Not using this type of collet chuck can result in damage to the power tool.

The use of thread formers is recommended, as the pull-out resistance and overtorque are significantly higher than when using machine taps.

Application

Application area

Suitable for use with drill presses and CNC machining centres

Automotive and agriculture

Construction, solar and heating industries

Stairs, railings and façades

Steel furniture and rehabilitation equipment

Instructions

Always clamp the friction drill bit fully into the collet chuck as far as it will go and screw the union nut tight. Check it after the first four to five holes and retighten if necessary.

Depth stop: Position the cutting edge of the drill bit flush with the workpiece surface, readjust if necessary

The workpiece being processed must be clamped horizontally and securely and not subject to vibration.

Ensure adequate cooling/lubrication and suitable speed!

Position the drill bit gently against the surface, then steadily build up pressure. The material being processed is heated and melted.

Quickly penetrate the material with the drill bit and shape the socket downwards. Do not interrupt the drilling process! The rule of thumb is a drilling time of approx. 1 second per 1 mm wall thickness.

In order to remove the collar, the feed speed should be significantly increased at the end. Caution: The removed chip will then fly out - it is essential to wear appropriate protective clothing.

When the depth stop is reached, move the drill bit out again immediately. If the friction drill bit rotates on the spot for too long, the material will overheat!

Caution: Do not touch the hot drill bit or the heated workpiece with your hands (only use the appropriate tool or protective gloves)!

Collet chuck set For use in tool holder for thermic drill bit

COLLETSET-F.DBIT-4PCS

Art.-no. 0618410001

Set, 4 pieces, for thermic drill bits with 6-12 mm mount. The collet chucks are made of high-quality material as thermic drill bit use generates very high temperatures (700-800°C). Lower-quality collet chucks could be damaged or make loosening of the drill bit impossible.
