🔍Roof-Top Diamond Drill Bit Segment – Heavy-Duty Concrete Drilling
Roof-top shaped diamond drill bit segment for hard concrete and deep hole drilling. High diamond concentration for maximum penetration in dense aggregate.
The Kowis Roof-Top Drill Bit Segment features an angled peak profile that concentrates cutting force at the center, like a roof ridge, delivering faster penetration in hard, dense concrete. High diamond concentration and a wear-resistant bond make this segment the first choice for deep hole drilling and heavy-duty concrete work where other shapes stall.
Segment Profile
- Shape: Roof-top (peaked center)
- Concentration: High diamond content
- Bond hardness: Medium-hard (matched to hard concrete)
- Available heights: 8mm / 10mm / 12mm / 15mm
Best Suited For
- Deep hole drilling in hard concrete
- Heavy-duty concrete drilling on dense aggregate
- Granite and hard stone drilling
- Reinforced concrete drilling (medium rebar)
When to Choose the Roof-Top Shape
Pick the roof-top segment when you need concentrated penetration force and you are working with hard concrete or dense aggregate. If you are drilling heavily reinforced concrete with frequent rebar, step up to the Grid Roof-Top for better wear resistance. If you need smoother contact and finish, the Flat segment is a better fit.
