Garrett Hill of The View, Gleann na Ri, Tower, Blarney was sentenced at Cork Circuit Court earlier this month.
The 38-year-old man had pleaded guilty to charges of having heroin for sale or supply at Cork Builders Providers car park in Togher on August 25, 2016, and having heroin for sale or supply at an apartment at Blarney shopping centre on the same date.
He also pleaded guilty to drug dealing at his home in Blarney in January 2017, after cannabis, cocaine and a quantity of heroin were seized by gardaí.
The latter incident occurred while he was on bail relating to the August 2016 charges.
He was given a seven-year sentence relating to the 2016 charges, and a consecutive term of 10 years for the January 2017 offence, totalling 17 years.
During the January 2017 operation, gardaí had observed him weighing drugs on a scales in his home.
The sentencing hearing took place at Cork Circuit Court on July 3.
On July 17, Mr Hill lodged an appeal application to challenge the length of his sentence, with the Courts Service. No date has yet been set for a hearing.
At his sentencing hearing, he was described as a significant drugs wholesaler by gardaí.
Judge Brian O’Callaghan said he was a cog in a “particular wheel”, “a wheel of death, a wheel of destruction”.
He said heroin is the most serious drug in the country and causes “nothing but destruction where it goes”.
