Drill Bit Set ALPEN SDS+ FORCE X Mix Box 7 pcs — model 815/835, SDS+ shank

ALPEN SDS+ FORCE X Mix Box 7 pcs — model 815/835 is a mixed set of SDS+ drill bits engineered for use with SDS+ rotary hammers. The set contains seven bits in a combination of the 815 and 835 models with SDS+ shanks, providing secure engagement in hammer drills and reliable performance when working on concrete, masonry and other hard substrates. Designed for applications that require hammer action and rotating drilling, these bits are suitable for both professional tradespeople and informed DIY users.

Advantages

The mixed set offers immediate access to several commonly used lengths and geometries without the need to purchase individual sizes. SDS+ shanks ensure positive, slip-free connection to compatible rotary hammers, while the FORCE X design focuses on improved impact transfer and optimized tip geometry for effective material penetration. The combination of models in one box reduces downtime and simplifies bit selection on site.

Suitable for

• Drilling holes in concrete for anchors and fixings
• Making openings in masonry and brickwork
• Preparing holes for electrical and plumbing installations
• General hammer-drilling tasks with SDS+ rotary hammers

Key specifications

• Set composition: 7 SDS+ bits in mixed lengths/models (815 and 835)
• Shank type: SDS+ for secure tool coupling
• Intended materials: concrete, masonry, brick and similar hard substrates
• Application mode: hammer drilling with rotary hammer tools
• Design focus: enhanced impact transfer and optimized tip geometry for penetration

How to use

Select the appropriate bit from the Mix Box for the required hole diameter and depth. Insert the SDS+ shank into the rotary hammer's chuck until it locks; verify the bit is secure before starting. Use the rotary hammer in hammer-drilling mode for concrete and masonry, applying steady pressure without excessive force. Withdraw the bit periodically to clear debris and prevent overheating. For through-holes, work progressively with pilot and finishing sizes as needed.

Usage recommendations

Wear appropriate personal protective equipment, including safety glasses, hearing protection and a dust mask when drilling. Match drill speed and hammer settings to the material and bit size, and avoid side loads that can damage the bit or tool. Store the bits in the original Mix Box to protect cutting edges and keep the set organized for future use.
