MAKITA D-06591 HSS-G Metal Drill Bit 10.50x133mm (5 pcs)

MAKITA D-06591  HSS-G Metal Drill Bit 10.50x133mm. (5 pcs)
Features: The D-06591 drill bit model belongs to Makita's HSS-G category, manufactured from High-Speed Steel (HSS) using a ground (Ground- G) process on both flutes and cutting edges according to the DIN338 standard. This production method provides exceptionally high dimensional and geometrical precision, resulting in efficient drilling and clean holes. The drill tip features a 118Ground Point  angle, which allows for fast drill starts and reduces walking. The 10.5 mm bit size is used for pilot holes for M12 thread tapping or holes for large bolts. 

Features
High Precision (HSS-G): Fully ground manufacturing provides sharp and highly precise cutting edges for clean drilling. Optimal Total/Working Length: Features a relatively long working length of 87 mm, suitable for drilling thick materials. 118  Ground Point: Enables fast drill starts, reduces feed pressure, and offers good cutting efficiency. Efficient Chip Evacuation: Well-ground flutes help continuously remove metal chips from the hole, reducing heat buildup. Heat Resistance: HSS material withstands wear and high heat in metal drilling well.

Application
The MAKITA D-06591 HSS-G drill bit is suitable for drilling 10.5  mm holes in the following materials: Steel and Cast Iron; Aluminum; Copper and Brass; Pilot hole for M12 tapping (standard size for coarse threads); Metal structural and maintenance work requiring large hole sizes.
