Drill bit AWTools AW43599 — single metal/wood drill bit, model AW43599

AWTools AW43599 is a single replacement drill bit intended for general drilling tasks in metal and wood, and is also designed to handle harder construction materials when used appropriately. Constructed from 40CR alloy steel with a YG8C carbide tipped blade, the AW43599 features a centering point with a 130° point angle and a double spiral flute for efficient material removal. The drill bit includes a grooved SDS+ shank to reduce the risk of accidental release when used with compatible hammer drills and rotary hammers.

Advantages

The combination of 40CR alloy steel body and a YG8C carbide tip provides enhanced wear resistance and cutting stability for repeated use. The 130° centering point improves positioning accuracy and reduces walking on the workpiece. Double spiral flutes promote effective chip evacuation and help limit overheating and vibration during operation. Four cutting edges deliver smoother holes and reduce the chance of jamming when encountering reinforcement such as rebar. The SDS+ grooved shank ensures secure retention in compatible tool chucks.

Suitable for

• General drilling in wood and metal with hand drills and drill presses
• Drilling in concrete, reinforced concrete and brick when used with hammer drills or rotary hammers
• Repair and assembly work on construction sites and in workshops
• Tasks requiring precise centering and smooth hole finishes

Key specifications

• Material: 40CR alloy steel body with YG8C carbide tipped blade
• Point angle: 130° centering point
• Flute design: double spiral for chip evacuation
• Cutting geometry: four cutting edges for smooth holes
• Shank type: grooved SDS+ shank for secure retention
• Suitable tool types: hand drills, drill presses, hammer drills, rotary hammers

How to use

Select a drill or hammer drill compatible with an SDS+ shank and secure the AW43599 bit according to the tool manufacturer’s instructions. Mark and center the drilling location, then start drilling at low speed to establish the hole before increasing speed or engaging hammer action as appropriate for the material. Apply steady, controlled pressure and allow the flutes to evacuate chips; withdraw the bit periodically from deep holes to clear debris and reduce heat buildup. For drilling in metal or wood use rotary action only, and for masonry materials use hammer action where supported by the tool.

Usage recommendations

Use appropriate personal protective equipment, such as safety glasses and hearing protection. Match the bit to the correct drill type and speed for the material. For prolonged drilling in hard materials, allow cooling pauses and clear chips frequently to extend bit life.
