From real customer feedback and reviews

Drill Bit: 113# FS Spiral PDC Drill Bit, Import Grade A Formation: Limestone Drilling Rig: 150 Drilling Machine Location: Guiping, Guangxi, China Drilling Speed: 3 meters in 45 minutes Customer Feedback: The drill bit has a long service life when used normally.
Xie Jianping
Drill Bit: 91# FS Spiral Granite Drilling Rig Model: 350 Poly Dragon Drill with 200 Type Mud Pump Rock Type: Volcanic rock / Basalt, fractured Worksite Location: Nandan County, Hechi City, Guangxi Province Drilling Speed: 2 meters/hour, smooth drilling without jams Customer Feedback: Previously, using other brands of diamond drill bits, the drilling speed was less than 1 meter/hour with frequent jams. Conventional composite and alloy steel drill bits were completely ineffective.
Lai Kebin
Drill Bit: 94# FS Spiral PDC Double-Tube Bread Piece Drill Bit Affiliation: Directly Affiliated Design Institute of Sichuan Provincial Department of Water Resources Worksite Location: Xipu Town, Pidu District, Chengdu City, Sichuan Province Drilling Rig Model: XY-2 and 1TD Drilling Rig Rock Type: Hard sandstone, conglomerate, siliceous limestone, and dolomite Customer Feedback: One spiral double-tube drill bit drilled 180 meters with excellent coring results. Another bit reached 171 meters with minimal wear and is still in good condition for continued use. The coring performance was satisfactory. Previously used diamond bits wore out too quickly, while the FS bits yielded impressive results.

FS_Three-Wing_Concave_Reinforced_PDC_Custom_Combination_Drill_Bit
Drill Bit: 150220273 Three-Wing Concave Reinforced Combination Drill Site: Ganzhou, Jiangxi Drill Rig Model: 400 Stratum: Strongly Weathered Granite Customer Feedback: The penetration speed is fast, approximately three times that of geological exploration drills. The customer described it as cutting through material as easily as slicing vegetables and melons. Drilling over 100 meters a day is no problem, with almost no wear on the drill bit.
