Drill bit set Dedra WM05593 — 5.5 mm diameter, 93 mm length, 2 pcs, for metal

Dedra WM05593 drill bit set includes two high-speed steel (HSS) bits with a 5.5 mm cutting diameter and a 93 mm overall length, engineered for drilling metal. Designed for use in hand drills and drill presses, these bits produce precise through-holes in sheet metal, pipes and metal profiles. The set is intended for general maintenance, fabrication and metalworking tasks where a standard 5.5 mm metal drill is required.

Advantages

The HSS material offers good wear resistance and heat tolerance during metal drilling, helping to maintain cutting performance over repeated use. The 93 mm overall length provides sufficient reach for working through thin assemblies and into recessed areas while the 5.5 mm diameter matches common fastener sizes. Supplied as a pair, the set gives a spare bit for continuous work or for use with multiple tools.

Suitable for

• Drilling through sheet metal and metal panels
• Creating holes in metal pipes and tubular profiles
• Maintenance and repair tasks on machinery and equipment
• Light fabrication and metalworking projects requiring 5.5 mm holes

Key specifications

• Cutting diameter: 5.5 mm
• Overall length: 93 mm
• Material compatibility: metal (suitable for steel, mild steel and similar ferrous materials)
• Number of pieces: 2
• Shank type: straight round shank (fits standard drill chucks)

How to use

Mark the drilling position and secure the workpiece to prevent movement. Select an appropriate drill speed for metal and, if possible, use cutting fluid to reduce heat and prolong bit life. Insert the 5.5 mm bit into the drill chuck and tighten securely. Start drilling at low speed to establish the hole, then increase speed as needed while applying steady, even pressure. Withdraw the bit occasionally to clear chips and allow cooling. Replace the second bit if the first shows signs of wear or damage.

Usage recommendations

Use the Dedra 5.5 mm HSS bits with proper personal protective equipment, including safety glasses and gloves. For harder or thicker steel, use cutting fluid and moderate speeds to prevent overheating. Store bits in a dry place and avoid striking the cutting edge to maintain performance and longevity.
