Drill Bit Makita SDS Economy 10 x 350 mm, SDS-plus rotary hammer bit for concrete and masonry

Makita SDS Economy 10 x 350 mm is an SDS‑plus rotary hammer drill bit designed for drilling deep holes in concrete, masonry and natural stone. With a 10 mm carbide tip diameter and 350 mm overall length it enables drilling for through‑holes, anchor installation and conduit passages when used with SDS‑plus rotary hammer drills. The Economy line provides a practical balance of performance and cost for general construction and installation tasks.

Advantages

The SDS‑plus shank ensures quick, secure connection to compatible rotary hammer drills and efficient energy transfer for percussive drilling. The 350 mm length offers extended reach for deep or pass‑through holes while the 10 mm diameter suits standard fasteners and anchors. Carbide tip geometry is optimized for concrete and masonry, delivering reasonable drilling speed and wear resistance for routine jobs.

Suitable for

• Drilling anchor holes in concrete and block for fixings and fasteners
• Creating through‑holes for cables, pipes or conduits in masonry
• General construction and renovation tasks requiring deep 10 mm holes
• Work with SDS‑plus rotary hammer drills in professional or DIY settings

When it may not be suitable

This drill bit is not intended for use in metal, wood or ceramic tiles; using it on those materials will reduce performance and may damage the tip. For high‑volume production drilling or heavy demolition work a professional‑grade or carbide‑reinforced series with enhanced durability may be more appropriate.

Key specifications

• Tip diameter: 10 mm
• Overall length: 350 mm
• Shank type: SDS‑plus
• Intended materials: concrete, masonry, natural stone
• Tip material: carbide (for masonry applications)

How to use

Fit the SDS‑plus shank securely into the rotary hammer chuck until it locks. Select an appropriate hammer mode (percussive drilling) on the tool and start drilling with steady pressure, allowing the tool to advance the bit without forcing it. For through‑holes, periodically withdraw the bit to clear dust and debris and maintain cooling. Use appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask when drilling masonry or concrete.

What to consider before purchase

• Ensure your rotary hammer supports SDS‑plus shanks
• Confirm 10 mm diameter and 350 mm length meet your anchor or through‑hole requirements
• Choose a higher‑grade or longer‑life bit for frequent heavy‑duty use
• Check accessory compatibility (depth stops, extension sleeves) if needed

Usage recommendations

For best results, use at the manufacturer recommended hammer setting, keep the bit clean of dust by withdrawing regularly, and replace the bit when cutting speed or accuracy declines. For drilling reinforcement or very hard aggregate, consider using a dedicated bit designed for reinforced concrete.
