## Summary description

Tungsten drill bits Dedra DED1515 presented as a set including 22 mm and 35 mm diameters. Designed for drilling with enhanced cutting hardness provided by tungsten tips, suitable for wood, plastics and some construction materials depending on working conditions. Useful for carpentry, installation and repair tasks where larger-diameter holes are required; compatible with standard drill chucks.

## Long description

Tungsten drill bit Dedra DED1515 22 mm and 35 mm set is a two-piece collection of large-diameter drill bits designed for use with standard drill chucks. Each bit features a tungsten-enhanced tip to increase cutting hardness and maintain edge life when working with wood, plastics and certain construction materials under appropriate conditions. The set covers common big-hole needs in carpentry, installation and repair tasks where durable, larger-diameter drilling tools are required.
Advantages
The tungsten-enhanced tips provide increased wear resistance compared with standard carbon-steel bits, extending useful life during repetitive drilling. The set includes two diameters—22 mm and 35 mm—which reduces the need to change tools for different hole sizes. Designed for compatibility with standard chucks, the bits are easy to install and remove on most hand and corded drills. The geometry of the cutting edges helps to produce cleaner holes in wood and plastics and to reduce tear-out when used with appropriate feed rates.
Suitable for
 Carpentry and woodworking where larger holes for dowels, pipes or cable pass-throughs are needed
 Installation work such as mounting fixtures, running cables or creating conduit openings
 Repair and maintenance tasks that require quick large-diameter drilling in timber and composite materials
 DIY projects that involve cutting clean holes in soft-to-medium density materials
Key specifications
 Set composition: two drill bits — 22 mm and 35 mm diameters
 Tip material: tungsten-enhanced cutting tip for improved hardness and wear resistance
 Compatible chuck type: standard drill chucks (suitable for most hand and corded drills)
 Main usable materials: wood, plastics and some construction materials depending on conditions
 Intended use: large-diameter hole drilling for carpentry, installation and repair
How to use
Install the selected bit securely in a properly rated drill chuck, ensuring the shank is clamped tightly and the drill is set to an appropriate speed for the material. Start drilling at low speed to create a starter groove, then increase speed and apply steady, even pressure without forcing the bit. Withdraw the bit periodically on deep holes to clear chips and reduce heat buildup. For best results in wood and plastics, support the workpiece and clamp it to prevent vibration and tear-out. Observe appropriate personal protective equipment such as eye protection and gloves.
Usage recommendations
Use lower to moderate drill speeds and controlled feed rates to preserve the tungsten-enhanced tip and avoid overheating. For cleaner edges in wood, consider backing the drilling area with sacrificial material or use a pilot hole when precise entry is required. Avoid prolonged use on reinforced concrete or masonry; select a purpose-built masonry bit for such materials.
