Hole saw Dedra 100 mm carbide (HM) with HEX shank DED1507-X

Dedra hole saw 100 mm carbide (HM) with HEX shank DED1507-X is a bi-metal-style cutting tool with a carbide cutting edge designed for creating clean round holes in a variety of common construction and installation materials. The 100 mm diameter tooth ring combined with a HEX shank provides a stable connection to drills and adapters that accept hexagonal shanks, allowing efficient hole cutting when a hard-wearing cutting edge is needed.

Advantages

The carbide (HM) cutting edge offers improved wear resistance compared with standard high-speed-steel teeth, extending the tool life during repetitive cutting tasks. The 100 mm diameter is suitable for larger openings such as pipe entries or electrical boxes, while the HEX shank improves grip in compatible chucks and quick-change adapters to reduce slippage. The design enables effective cutting in wood, many plastics and some non-ferrous metals when used with appropriate speeds and feed.

Suitable for

• Cutting circular openings for pipes and conduits in wooden structures
• Making holes for electrical and ventilation boxes
• Cutting holes in plastic panels and sheets
• Drilling largish holes in thin non-ferrous metal sheets (where carbide is suitable)
• Trade and construction site drilling tasks requiring durable cutting edges

Key specifications

• Cutting diameter: 100 mm
• Cutting edge material: carbide (HM)
• Shank type: HEX (hexagonal)
• Intended materials: wood, plastics, some non-ferrous metals
• Application area: construction, installation, trade

How to use

Install the hole saw onto a compatible arbor or directly into a drill chuck that accepts HEX shanks, ensuring a secure fit before operation. Mark the hole center on the workpiece and start drilling at low speed to establish the pilot location; increase speed and apply steady pressure suitable for the material being cut. Keep the tool perpendicular to the surface and clear chips regularly to avoid overheating. When cutting metals or dense plastics, use appropriate coolant or reduced feed speed to prolong cutter life.

Usage recommendations

Use appropriate personal protective equipment, such as safety glasses and gloves. Verify that the drill and any arbor used are rated for the hole saw diameter and the intended material. For prolonged life of the carbide edge, avoid excessive feed rates and overheating; when cutting metal or hard plastics, use cutting lubricant and moderate speeds.
